Various examples of tilting a human support surface in a vehicle are disclosed. A frame is attached to the surface of the vehicle. The vehicle also includes rotation system mounted between the frame and a vehicle surface. The rotation system can be controlled to tilt a human support surface of the frame towards a direction of acceleration associated with a driving maneuver as the driving maneuver is executed.

A seat for a motor vehicle includes a backrest part with a front side and rear side facing away from the front side. A backrest surface, which serves for supporting a back, is transversely divided into a central section and two lateral sections. A seat part includes a sliding mount for the backrest part to realize a translational motion of the backrest part relative to the seat part between a forward facing position and a rearward facing position. Two lateral sections form a lateral support for a person on the seat and/or the seat part as a two-piece seat part including a first section and a second section and an intermediate space. A bracket extends through the intermediate space.

The invention relates to a vehicle seat, in particular a utility motor vehicle seat, having a seat part, having a backrest comprising a lower backrest part and an upper backrest part, and having a holding device, by means of which the upper backrest part is mounted displaceably with respect to the lower backrest part, the holding device comprising a guide roller device, by means of which the upper backrest part is arranged laterally displaceably with respect to the lower backrest part along a displacement curve so as to mount the upper backrest part displaceably at least in part past the side edge of the lower backrest part.

A seat device with an exit assist function includes a seat cushion; a seat base plate configured to support a lower end of the seat cushion; an actuator unit configured to move the seat cushion; a weight sensor configured to detect a weight of an occupant; an exit assist button configured to provide an exit assist operation signal; and a controller configured to control the actuator unit. Upon receiving the exit assist operation signal, the controller receives weight data of the occupant from the weight sensor, sets an exit assist operation based on the weight data of the occupant, sets a control value of the actuator unit based on the set exit assist operation, and controls the seat cushion to move based on the control value of the actuator unit.

A seat system includes a front seat including a first seat portion and a second seat portion, a rear seat arranged in a front-rear direction and including a third seat portion and a fourth seat portion, a posture switching mechanism configured to implement a first switching for selectively switching to a rear end flat seat portion of the front seat facing the rear seat, and a second switching for selectively switching to a front end flat seat portion of the rear seat facing the front seat, and a front-rear slide mechanism configured to slide at least one of the front seat and the rear seat in the front-rear direction relative to a floor to align the rear end flat seat portion of the front seat to be flush with the front end flat seat portion of the rear seat in the front-rear direction.
