A seat and seat back assembly includes a seat back moveable between an upright position and a horizontal position. A support panel is connected to the seat back for pivoting movement of the support panel between a first position supporting the seat back upright, and a second position wherein the seat back is moveable into the horizontal position. A biasing mechanism serves to urge the support panel into the first position when the seat back is moved into an upright position. When the support panel is moved into the second position this allows the seat back assembly to move into the horizontal position without dropping unrestricted.

A vehicle seat includes a side frame, a cushion panel, and an insertion member. One of the side frame and the cushion panel is provided with an elastically deformed portion including an outer circumferential surface and an inner circumferential surface, the outer circumferential surface being configured to be expanded outward by insertion of the insertion member on the inner side of the inner circumferential surface. The other of the side frame and the cushion panel is provided with a recess forming portion facing the outer circumferential surface of the elastically deformed portion, the recess forming portion having an inner surface configured to be brought into pressure contact with the outer circumferential surface expanded by insertion of the insertion member.

Provided is a vehicle seat which is attached to a floor of a vehicle via a rail device and a coupling device with a high level of stiffness so as to minimize deformation of the rail device and the coupling device without substantially increasing the weight and the manufacturing cost of the seat. The vehicle seat is provided with an upper engagement portion secured to a member on a side of an upper rail of the rail device, and a lower engagement portion secured to a member on a side of a lower rail of the rail device and including a part opposing a corresponding part of the upper engagement portion from above defining a prescribed gap therebetween. The coupling device is provided laterally spaced from the rail device, and the upper engagement portion and the lower engagement portion are provided substantially directly above the coupling device.

A cable actuator system includes an actuating cable for connection to an actuator and to an actuatable device and a bypass assembly connected to the actuating cable. The bypass assembly includes a bypass input with a first input position and with a second input position. With the bypass input in the first input position the bypass assembly acts on the cable such that an actuating movement of the cable by the actuator moves the cable an actuating distance at the actuatable device to actuate the actuatable device. With the bypass input in the second input position the bypass assembly acts on the cable such that the actuating movement of the cable by the actuator does not move the cable the actuating distance at the actuatable device. A vehicle seat, with a seat base, a backrest, an actuator, and a vehicle seat actuatable device, also includes the cable actuator system.

The present invention has an object to provide a seat for vehicles in which a seat cushion flip-up mechanism can be space-saving. In a seat for vehicles which has a flip-up mechanism to shift a seat cushion frame (200) disposed on a base part (5) from a normal seating posture (200-1) to a flipped-up posture (200-2), the flip-up mechanism includes: a support leg part (301) having one end connected to the seat cushion frame (200) rotatably around a first rotation shaft (303) and the other end connected to the base part (5) rotatably around a second rotation shaft (302); a guide part (201a) to be engaged with the one end of the support leg part (301) to guide the one end so as to lift the one end; and a coil spring (305) applying a biasing force so as to have the one end guided by the guide part (201a) and flip up a portion (303) connected with the seat cushion frame (200).

A vehicle seat comprises: first and second risers to engage with respective first and second rails on a floor of a vehicle; a seatback extending from a first pivot at the first and second risers; and a seat cushion mounted to the first and second risers using a four-bar linkage, wherein the seat cushion is not attached to the seatback and is not supported by the seatback; wherein the vehicle seat has (i) a comfort position in which a latch holds the seat cushion in a first position relative to the seatback, the seat cushion supported only by the four-bar linkage in the first position, and (ii) a fold-flat position in which the four-bar linkage is folded to position the seat cushion toward the floor, and in which the seatback is folded about the first pivot and assumes a second position at least partially overlapping the seat cushion.

Provided is a vehicle seat which is attached to a floor of a vehicle via a rail device and a coupling device with a high level of stiffness so as to minimize deformation of the rail device and the coupling device without substantially increasing the weight and the manufacturing cost of the seat. The vehicle seat is provided with an upper engagement portion secured to a member on a side of an upper rail of the rail device, and a lower engagement portion secured to a member on a side of a lower rail of the rail device and including a part opposing a corresponding part of the upper engagement portion from above defining a prescribed gap therebetween. The coupling device is provided laterally spaced from the rail device, and the upper engagement portion and the lower engagement portion are provided substantially directly above the coupling device.

A seat (1, 1, 1) having a seat part (2), a backrest (3, 3, 3) and a head restraint (4). The backrest (3, 3, 3) is pivotable between a seat position (Si) and a forwardly folded position (S2) by a backrest adjustment unit (8), and the head restraint (4) is adjustable between a use position (K1) and a non-use position (K2) by the backrest adjustment unit (8) firstly opening a rotary fitting (32) or a latching fitting (26) of the backrest (3, 3, 3) and secondly adjusting the backrest (3, 3, 3) between the seat position (Si) and the forwardly folded position (S2), and, during pivoting of the backrest (3, 3, 3) from the seat position (S1) into the forwardly folded position (S2), the head restraint (4) is adjusted by an adjustment drive (9) into the non-use position (K2).

A vehicle seating assembly includes a mounting bracket, a seat, a seatback, and a cam assembly. The seat is rotatably coupled to the mounting bracket. The seatback is rotatably coupled to the mounting bracket. The seatback includes a protrusion. The cam assembly is rotatably coupled to the mounting bracket. The cam assembly includes a lockout cam having a first end and a second end. The first end of the lockout cam engages with the protrusion of the seatback such that movement of the seatback relative to the mounting bracket is restricted in a first non-use state. The second end of the lockout cam engages with the seat such that movement of the seat relative to the mounting bracket is restricted in a second non-use state.

A sliding interlocking reclining seat structure includes a seat cushion assembly configured to move forward and backward within a vehicle body, a rail assembly positioned on a lower end of the seat cushion assembly and configured so that the seat cushion assembly slides, a seatback assembly connected to the seat cushion assembly through a hinge part and configured to move in a height direction of the vehicle body in response to the sliding of the seat cushion assembly, and a latch assembly, disposed on an upper end of the seatback assembly, including a guide bracket having a slot formed therein in a height direction, and configured to be fastened to one end of a striker fixed to the vehicle body. While the seat cushion assembly slides, the latch assembly vertically moves along the slot when fastened to the striker, and the seatback assembly moves in the height direction of the vehicle body as the hinge part moves forward.
