A seat is disclosed herein having a backrest, a base for receiving a posterior of a human user, and an incline adjuster having a shaft, a lever, a follower, and a rack the shaft being moveable to swing the lever to cause a follower into or out of locking engagement with the rack, an arrangement being such that when the follower is in an unlocked disposition the rack can move to adjust an incline of the backrest and the base.

Provided is a robot including a main body including a traveling wheel, an accessory mounting portion and an opening, the opening being spaced apart from the accessory mounting portion, a rear sensor which is accommodated in the opening and facing a rear of the robot to sense outside of the main body, and an accessory including a mounter mounted on the accessory mounting portion and a supporter for supporting an article.

A piece of seating furniture with a base for setting up in a fixed position, a seating element tiltable in relation to the base and having a seating surface, and a leg support element movable in relation to the seating element and having a leg support surface. The leg support element is connected to the seating element via a link gear, wherein the leg support element is movable between a storage position and a use position via the link gear. An electric motor is provided below the seating surface, which acts on the link gear via a push rod. To connect the leg support element to the seating element, the link gear has a pivoting link which, during the transfer of the leg support element from the storage position into the use position, is arranged in part in a slot partially penetrating the leg support surface.

A configurable assistive device comprising: a platform; at least three wheels; and, at least three independent leg mechanisms, each respective leg mechanism coupled to the platform and a respective one of the at least three wheels, each respective leg mechanism configured to move the platform relative to the respective wheel for positioning the platform at an elevation and for inclining the platform to an inclination to configure the assistive device into one of a plurality of configurations.

A transfer apparatus for receiving the chair seat of a wheelchair and supporting the chair seat in the base of a washing enclosure. The transfer apparatus has a chair support member including a chair support track section that can be positioned in the washing enclosure base, a bridge portion with a bridge track section that is movably mounted to the chair support member. The transfer apparatus includes a lock system usable to secure the bridge portion in an in-use position and engaged with the wheelchair. A first lock inhibits rotational motion of the bridge portion. The first lock includes a retractable locking member that is biased to an extended, locking position. A second lock is usable to prevent longitudinal separation of the bridge portion and the wheelchair. The first and second lock can be automatically engaged when the bridge portion is moved to the in-use position.

A pedal-powered wheelchair having a steering dolly pivotally mounted at a rear of the wheelchair. When the upper end of a first steering lever is pulled and the upper end of a second steering lever is pushed, a first steering linkage connected to the first steering lever pulls forward a first side of the steering dolly and a second steering linkage connected to the second steering lever pushes rearward a second side of the steering dolly. This causes the steering dolly to turn clockwise to initiate a left turn. When the upper end of the first steering lever is pushed and the upper end of the second steering lever is pulled, the first steering linkage pushes rearward the first side of the steering dolly and the second steering linkage pulls forward the second side of the steering dolly. This causes the steering dolly to turn counterclockwise to initiate a right turn.

A system for controlling a wheelchair is disclosed. The system includes an input device that includes a shaft element, a base element, and one or more annular elements. A lower distal end of the shaft element is coupled to the base element, and the shaft element is configured to pivotally move about the lower distal end of the shaft element. A first annular element of the one or more annular elements is circumferentially disposed around the shaft element. The first annular element is coupled to the base element, and the first annular element is configured to rotate about the shaft element. The input device is configured to generate one or more input signals based on a position of the first annular element and a pivotal movement of the shaft element. The one or more input signals are configured to cause a controller to set an operation mode of the wheelchair.

The invention relates to means for releasably connecting a wheelchair backrest to a wheelchair frame. This is desirable to facilitate collapse of the wheelchair for transport or storage. In the preferred embodiment there is a wheelchair having a support frame, a backrest (16) and connector comprising a saddle (1) and a clamp (17). The saddle has a slot (3) with top and front openings and a locking lever (7). Two pins (12) are received in the slot so they extend through the front opening, and the lever (7) is able to move to divide the slot into top and bottom zones so that a lower one of the pins is prevented from being withdrawn from the slot via the top opening by the lever. The lever can then be moved to unblock the lower pin and allow the slot (3) and the pins (12) to be dissociated.

An automated adjustable seating system (10) comprising: a seat (16), the seat (16) incorporating a first sliding frame (62) and seat upholstery attached to the sliding frame (62); a backrest (20), the backrest (20) incorporating a second sliding frame (138) and back upholstery attached to the sliding frame (138); a set of actuators (106, 128, 194, 196, 198); and a control system (200). The set of actuators (106, 128, 194, 196, 198) includes an actuator for adjusting the angle of the seat (16) relative to the horizontal (194), an actuator (106) for adjusting the longitudinal position of the first sliding frame (62); an actuator (196) for adjusting the angle of the backrest (20) relative to the vertical and an actuator (198) for adjusting the longitudinal position of the second sliding frame (138). Each of the set of actuators (106, 128, 194, 196, 198) is controlled by the control system (200).

A wheelchair includes a seating portion on which a wheelchair user sits, a body frame that supports the seating portion, a pair of rear wheels and a pair of front wheels rotatably supported by the body frame, and a seat back portion capable of changing the inclination angle with respect to the seating portion. The wheelchair includes push-along handle portions as engaging portions capable of fixing the seat back portion to a side sill as a vehicle body member that forms a door opening of the vehicle when the seat back portion is tilted backward of the wheelchair.
