DETAILED DESCRIPTION OF THE INVENTION

(10) For purposes of the description hereinafter, the terms “end”, “upper”, “lower”, “right”, “left”, “vertical”, “horizontal”, “top”, “bottom”, “lateral”, “longitudinal”, “fore/aft”, and derivatives thereof shall relate to the invention as it is oriented in the drawing figures. However, it is to be understood that the invention may assume various alternative variations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the invention. Hence, specific dimensions and other physical characteristics related to the embodiments disclosed herein are not to be considered as limiting.

(11) With reference to FIGS. 1 and 2, an operating control for a six way power transfer seat is shown in accordance with an embodiment of the present invention. The operating control includes a user control interface box 10 having a user control interface box body 11, which provides a user interface for controlling movement of the power transfer seat. The user control interface box body 11 is divided into a first portion including the forward half 13 of the body 11 and a second portion including the rearward half 12 of the body 11. The rearward half 12 of the user control interface box body 11 includes a directional control switch 14. As shown, the directional control switch 14 includes a joystick switch having a lever located on the side of the user control interface box body 11 and extending laterally from the user control interface box body 11. The lever is movable along a vertical direction as indicated by the arrow A shown in FIG. 2 and a horizontal fore/aft direction as indicated by the arrow B shown in FIG. 2. The joystick switch 14 is actuated to control both the forward and rearward movement and the upward and downward movement functions of the power transfer seat. Moving the lever of the joystick switch 14 forward makes the base of the seat move forward, moving the lever up makes the base go up, and so on. The forward half 13 of the user control interface box body 11 includes at least one rotation control switch 15, which includes a knob attached to a top side of the user control interface box body 11 and rotatable about a vertical axis as indicated by the arrow C shown in FIG. 2. The at least one rotation control switch 15 is actuated to control rotational movement of the power transfer seat about a vertical axis. Rotating the knob of the at least one rotation control switch 15 clockwise makes the seat rotate clockwise and vice versa. In another preferred and non-limiting embodiment, the joystick switch 14 is located on a first portion of the user control interface box body 11, and the at least one rotation control switch 15 is located on a second, different portion of the user control interface box body 11. Further, the joystick switch 14 and/or the rotation control switch 15 can be configured to be actuated to control any specified movement of the power transfer seat, including, but not limited to, forward movement, rearward movement, upward movement, downward movement, rotation movement about a vertical axis, rotation movement about a horizontal axis, and/or any other desired movement of the power transfer seat.

(12) In one preferred and non-limiting embodiment, the shapes of the rearward and forward halves 12, 13 (or different portions) of the user control interface box body 11 are shaped differently in order to provide the user with further tactile information when the user reaches for the joystick and rotation control switches 14, 15. The combination of the laterally oriented joystick switch 14 and the rotation control switch 15 makes an arrangement that is more tactilely intuitive than previous iterations. Moreover, as the joystick switch 14 controls both forward and rearward and upward and downward movement, the number of choices that the user has to make in engaging a switch has been limited, thereby making it nearly impossible for the user to pick the wrong switch.

(13) Because the user interface provided by the operating control is simpler to operate, it may also be more susceptible to inadvertent operation. In order to mitigate this eventuality, and in one preferred and non-limiting embodiment, one or more protective elements are also provided on the user control interface box body 11 to prevent or limit inadvertent operation. As shown in FIG. 2, at least one, and preferably multiple (e.g., two) protrusions 17 are mounted parallel to the axis of the knob of the at least one rotation control switch 15 that serve the dual purpose of limiting the travel of the rotation control switch 15, thereby preventing the overloading of the switch by the operator, and protecting the rotation control switch 15 from damage while the operator is moving from the wheelchair to the vehicle driver's seat. Further, such protrusions 17 may be shaped or contoured to be comfortably contacted or gripped by the user, while still providing access to the rotation control switch 15. In addition, protrusions or other protective elements may be located on or near the joystick switch 14 to provide similar protection.

(14) In another preferred and non-limiting embodiment, the lever or bat of the joystick switch 14 is spring loaded such that, in the event a blow is taken by the joystick switch 14 along the axis of the lever, the joystick switch 14 can compress into a protective housing 16 formed in the rearward half 12 of the user control interface box body 11. Additionally, the surrounding protective housing 16 of the joystick switch 14 is spaced such that, in the event the joystick switch 14 is displaced in any direction, it can only move just past the actuation point of the joystick switch 14 before contact is made between the lever of the joystick switch 14 and the protective housing 16, thereby protecting the joystick switch 14 from damage when the operator is moving from the wheelchair to the vehicle driver's seat.

(15) With reference to FIG. 1A, an operating control for a six way power transfer seat is shown in accordance with another embodiment of the present invention. The operating control illustrated in FIG. 1A operates according to the same principles as the operating control described above with reference to FIGS. 1 and 2, but provides a different configuration of controls. In particular, the operating control includes a user control interface box 10A having a user control interface box body 11A, which provides a user interface for controlling movement of a power transfer seat. The user control interface box body 11A is divided into a first portion including the forward half 13A of the body 11A and a second portion including the rearward half 12A of the body 11A. The rearward half 12A of the user control interface box body 11A includes a directional control switch 14A in the form of a D-pad switch. As shown, the D-pad switch 14A includes a segmented button or, alternatively, multiple buttons, which is/are arranged so that pressing on/actuation of a particular portion of the button or on an individual button controls the power transfer seat to move in a direction corresponding to the position of the portion of the button or individual button being pressed/actuated. Accordingly, pressing or actuating the upper portion of the D-pad switch 14A causes the power transfer seat to move upward, pressing or actuating the lower portion of the D-pad switch 14A causes the power transfer seat to move downward, pressing or actuating the forward portion of the D-pad switch 14A causes the power transfer seat to move forward, and pressing or actuating the rearward portion of the D-pad switch 14A causes the power transfer seat to move rearward. In this manner, the D-pad switch 14A is actuated to control both the forward and rearward movement and the upward and downward movement functions of the power transfer seat. The forward half 13A of the user control interface box body 11A includes at least one rotation control switch, which includes two push button switches 15A, 15B. Each push button switch 15A, 15B is configured to be actuated to control movement of the power transfer seat in one direction of rotation about the vertical axis. Pressing or actuating the push button switch 15A with the right pointing arrow causes the power transfer seat to rotate clockwise about the vertical axis, and pressing or actuating the push button switch 15B with the left pointing arrow causes the power transfer seat to rotate counterclockwise about the vertical axis. It is to be appreciated that the D-pad switch 14A and/or the push button rotation control switches 15A, 15B can be configured to be actuated to control any specified movement of the power transfer seat, including, but not limited to, forward movement, rearward movement, upward movement, downward movement, rotation movement about a vertical axis, rotation movement about a horizontal axis, and/or any other desired movement of the power transfer seat. As in the embodiment of the operating control discussed above with reference to FIGS. 1 and 2, the rearward and forward halves 12A, 13A of the user control interface box body 11A may be shaped differently to provide the user with further tactile information when the user reaches to press the D-pad switch 14A and/or the push button rotation control switches 15A, 15B. It is to be appreciated that the user control interface box body 11A may include one or more protective elements provided to protect the D-pad switch 14A and the push button rotation control switches 15A, 15B from inadvertent operation and damage. For instance, as shown in FIG. 1A, the push button rotation control switches 15A, 15B are recessed within the user control interface box body 11A.

(16) It is to be appreciated with respect to both of the embodiment of FIGS. 1 and 2, and the embodiment of FIG. 1A, that the user control interface box body 11, 11A is configurable for both driver and passenger side applications. In other words, the at least one rotation control switch 15, 15A, 15B may be moved from one side of the user control interface box body 11, 11A to the other and the jumpers of the directional control switch 14, 14A may be swapped so that the user control interface box 10, 10A may be positioned on either one of the left side or the right side of the power transfer seat base.

(17) With reference to FIGS. 3 and 4, according to an additional preferred and non-limiting embodiment of the present invention, the operating control may be provided with a CAN-based vehicle interlock system 100 that disables the operating control when the vehicle is in motion. Modern automotive control systems are based on a series of vehicle mounted computer systems. These computers communicate with each other over a network referred to as a Controller Area Network (CAN) 101. CAN is a vehicle communications bus standard designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer. CAN bus is a message-based protocol, designed specifically for automotive applications.

(18) As described above, it is desirable for the operating control of the power transfer seat to be interlocked with the vehicle so that the transfer seat controls are disabled when the vehicle is not parked. To accomplish the vehicle interlock, and in one preferred and non-limiting embodiment, the operating control is provided with a microcontroller 102 capable of monitoring signals moving across the vehicle CAN 101, which are transmitted over the CAN by a vehicle transmission 103 or any other component of the CAN 101. By monitoring the CAN 101 for the absence of the vehicle's “PARK” signal, the microcontroller 102 provides a signal to the operating control that disables the transfer seat controls. In particular, the microcontroller 102 is in communication with the at least one rotation control switch 15 and the directional control switch 14 of the operating control. The microcontroller 102 monitors the CAN 101 to detect the presence of a “PARK” signal transmitted over the CAN 101 by the vehicle transmission 103 or other vehicle component in communication with the CAN 101. When the “PARK” signal is not present over the CAN 101, the microcontroller 102 disables operation of the operating control based on actuation of the at least one rotation control switch 15 or the directional control switch 14.

(19) FIG. 4 illustrates a schematic of the interlock process performed by the CAN-based interlock system 100, particularly the microcontroller 102, to engage or disengage the interlock to disable or enable operating of the operating control, in accordance with another preferred and non-limiting embodiment of the present invention. In an initial step 104, the microcontroller 102 monitors the CAN 101 for the presence of the “PARK” signal sent by the vehicle transmission 103. In a following step 105, the microcontroller 102 determines whether the “PARK” signal is transmitted over the CAN 101. If the microcontroller 102 determines that the “PARK” signal is transmitted over the CAN 101, as indicated by step 106, the microcontroller 102 proceeds to step 108 to enable functioning of the operating control in response to actuation of the at least one rotation control switch 15 and/or the directional control switch 14. The process then returns to the initial monitoring step 104. If the microcontroller 102 determines that the “PARK” signal is not transmitted over the CAN 101, as indicated by step 107, the microcontroller 102 proceeds to step 109 to disable functioning of the operating control in response to actuation of the at least one rotation control switch 15 and/or the directional control switch 14. The process then returns to the initial monitoring step 104. It is to be appreciated that the process detailed in FIG. 4 is exemplary only. The CAN-based interlock system 100 may be configured and programmed in any manner known to be suitable to those having ordinary skill in the art to provide interlock capability to the operating control.

(20) With reference to FIGS. 5-8, a configurable power transfer seat base 20 is shown in accordance with another preferred and non-limiting embodiment of the present invention. Given that it may be desired to install the seat base 20 in either the driver's or front passenger's positions, the power transfer seat base 20 is designed to permit the rotate function and the mounting of the user control interface box body 11 to be field-configurable. Most commonly, the transfer seat base 20 will be installed in the driver's position (on the left-hand side of the vehicle) and will be configured to rotate clockwise (as oriented from above the seat looking down) away from the driver's position and back again. In the event the seat is to be moved to the passenger side (on the right-hand side of the vehicle), the power transfer seat base 20 must be reconfigured to rotate in the opposite direction.

(21) As shown in FIGS. 5-7, the power transfer seat base 20 includes, amongst other components, a top fixed plate 21, a rotating plate 22 rotatably mounted above the top fixed plate 21, and a user control interface box mounting bracket 25 for mounting the user control interface box 10 to the power transfer seat base 20. The rotating plate 22 is configured so that the user control interface box mounting bracket 25 and at least one rotating stop 24 may be connected to the rotating plate 22 at different positions. The rotating plate 22 is provided with mounting holes 26 on both lateral sides thereof for attachment of the mounting bracket 25, and, thus, the user control interface box 10 mounted on the user control interface box mounting bracket 25, to the rotating plate 22. At least one, and preferably multiple (e.g., two) fixed stops 23 are mechanically attached on an upper surface of the top fixed plate 21 and the at least one rotating stop 24 is fastened to a bottom surface of the rotating plate 22 where the rotating plate 22 engages the top fixed plate 21. The rotating plate 22 is provided with mounting holes 27 formed on opposing lateral sides of the bottom surface thereof for attachment of the at least one rotating stop 24 to the rotating plate 22. The fixed stops 23 on the top fixed plate 21 are configured to engage the at least one rotating stop 24 on the rotating plate 22 to stop rotation of the rotating plate 22 with respect to the top fixed plate 21 in a given direction of rotation. Accordingly, providing two fixed stops 23 on the upper surface of the top fixed plate 21, as shown in FIG. 6, and one rotating stop 27 on the bottom surface of the rotating plate 22, as shown in FIG. 7, limits rotational movement of the rotating plate 22, and, thus, the power transfer seat, between a position wherein the power transfer seat faces in the forward direction of the vehicle and a position wherein the power transfer seat is oriented laterally to allow for entry and exit of the vehicle.

(22) The power transfer seat base 20 is reconfigured to change the direction of rotation by moving the rotating stop 24 from one lateral side of the rotating plate 22 to the other, as shown in FIG. 7; moving the user control interface box mounting bracket 25 from one lateral side of the rotating plate 22 to the other side; and moving the user control interface box 10 by inverting the rotation control switch 15 and changing a jumper on the joystick switch 14 to maintain the correct orientation of the raise/lower function. Of course, it is envisioned that the fixed stops 23 and/or the rotating stops 24 may be positioned to allow the seat to be moved to any desirable position within or in connection with the vehicle. In addition, the mounting bracket 25 may be configured for use in a variety of applications and to suit any particular user. As such, the mounting bracket 25 may be adjustable, rotatable, removably detachable, or any other configuration to allow for the adjustment and/or movement of the mounting bracket 25 and/or the user control interface box 10.

(23) As shown in FIGS. 5 and 8, the power transfer seat base 20 also includes a mounting system 30 for the power transfer seat base 20, which is shown in accordance with yet another preferred and non-limiting embodiment of the present invention. The mounting system 30 is configurable so that the power transfer seat base 20 may be installed in a variety of vehicles. In particular, the mounting system 30 includes at least one, and preferably multiple (e.g., two) removable cross members 31 that accommodate variation in the mounting position of the base 20 in the fore/aft direction of the vehicle by being connectable to attachment brackets 34 provided on the power transfer seat base 20 at multiple positions. The mounting system 30 also includes at least one, and preferably multiple (e.g., two) movable hooks 36 that accommodate variation in the mounting position of the base 20 in the lateral (e.g., right/left direction) by connecting the removable cross members 31 and/or the power transfer seat base 20 to the vehicle in a manner that allows for different side-to-side spacing. The mounting system 30 may further include at least one, and preferably multiple (e.g., two) movable forks 40 that cooperate with the movable hooks 36 to mount the power transfer seat base 20 to the vehicle in a manner that accommodates variation in the mounting position of the base 20 in the lateral direction.

(24) In particular, the removable cross members 31 are connected to the power transfer seat base 20 at different locations in the fore/aft direction and the movable hooks 36 are attached to the power transfer seat base 20 and at least one of the removable cross members 31 at different locations in the lateral direction. The mounting system 30 includes the attachment brackets 34 disposed on the power transfer seat base 20. Each of the attachment brackets 34 is connected to a respective one of the removable cross members 31. According to one embodiment, two attachment brackets 34, one bracket 34 provided on each lateral side of the base 20, are provided for connection to each of the removable cross members 31 provided. Thus, in the embodiment illustrated in FIG. 5, the mounting system 30 is provided with two removable cross members 31 spaced apart in the fore/aft direction and four corresponding attachment brackets 34. Each of the attachment brackets 34 includes a plurality of adjustment holes 35 defined therein, which are spaced apart in the fore/aft direction. Each of the attachment brackets 34 is connected to the respective one of the removable cross members 31 by at least one fastener 33 engaging holes 32 formed in a portion of the respective removable cross member 31 and at least one of the plurality of adjustment holes 35 formed in the attachment bracket 34. In this manner, the position of the power transfer seat base 20 with respect to the removable cross members 31 in the fore/aft direction may be adjusted or configured by selecting which of the plurality of adjustment holes 35 of the attachment brackets 34 are to be engaged with fasteners 33 to connect the removable cross members 31 to the power transfer seat base 20.

(25) At least one of the removable cross members 31 may include at least two sets of adjustment holes 39 defined therein at opposite lateral ends of the removable cross member 31, which extend through the removable cross member 31. The adjustment holes 39 of each set are spaced apart in the lateral direction. Each of the movable hooks 36 is connected to a respective one of the removable cross members 31 by at least one fastener 38 engaging the movable hook 36 and at least one of the adjustment holes 39 in the set of adjustment holes 39 in the respective end of the removable cross member 31. As shown in FIG. 8, the fastener 38 is a bolt that engages the movable hook 36, passes through the selected attachment hole 39 in the removable cross member 31, and then engages an attachment plate 37 that is slid over an end of the movable hook 36 to rigidly connect the movable hook 36 to the removable cross member 31. In this manner, the position of the removable cross members 31, and, thus, the power transfer seat base 20, in the lateral direction may be adjusted or configured by selecting which of the plurality of adjustment holes 39 of the removable cross member 31 are to be engaged with the bolts 38 to connect the removable cross member 31 to the movable hooks 36. As discussed above, the mounting system 30 may also include at least one and preferably multiple, e.g., two, movable forks 40 that are configured to be attached by fasteners 41 to a rear of the power transfer seat base 20 at different locations in the lateral direction.

(26) It is to be appreciated that the movable hooks 36, movable forks 40, and/or the removable cross members 31 are connected, directly or indirectly, to existing mooring points built in the vehicle floor. Since different vehicles are likely to have different types and configurations of mooring points, prior art mounting systems for power transfer seats had to be individually configured for a variety of different vehicle configurations. The mounting system 30 of the present invention may avoid the necessity of providing differently configured mounting systems for a variety of vehicles by making the connections between the elements of the mounting system 30 and the power seat transfer base 20 adjustable and configurable. Alternatively, the mounting system 30 may include a vehicle specific installation kit.

(27) With reference to FIGS. 5-8, according to one other preferred and non-limiting embodiment of the present invention, a method of assembling a power transfer seat base 20 is provided. The method includes providing a power transfer seat base 20 having a top fixed plate 21, at least one fixed stop 23 connected to an upper surface of the top fixed plate 21, a rotating plate 22, at least one rotating stop 24 connected to a bottom surface of the rotating plate 22, a user control interface box mounting bracket 25 configured to be mounted on the rotating plate 22, and a mounting system 30 for the power transfer seat base 20, which includes at least one removable cross member 31 and at least one movable hook 36. The method further includes selecting one of a right side configuration and a left side configuration for the power transfer seat base 20, attaching the at least one rotating stop 24 to a side of the bottom surface of the rotating plate 22 based on the selection of one of the right side configuration and the left side configuration, mounting the user control interface box mounting bracket 25 on a side of the rotating plate 22 based on the selection of one of the right side configuration and the left side configuration, rotatably mounting the rotating plate 22 to the top fixed plate 21, selecting a position of the power transfer seat base 20 and the at least one removable cross member 31 with respect to the at least one movable hook 36 in a lateral direction, attaching the at least one movable hook 36 to the power transfer seat base 20 and the at least one removable cross member 31 based on the selected position in the lateral direction, selecting a position of the power transfer seat base 20 with respect to the at least one removable cross member 31 in a fore/aft direction, and attaching the at least one removable cross member 31 to the power transfer seat base 20 based on the selected position in the fore/aft direction.
