A vehicle passenger seat assembly includes a passenger seat and a rail system. The passenger seat includes a seat base and a seat back connected to the seat base. The passenger seat is movable between a seated condition for accommodating a seated passenger and non-seated condition where the passenger seat is tilted forward in a front-rear direction of the vehicle about a forward end portion of the seat base. The rail system is mounted to the seat base and configured to have mounted thereto a child car seat. The rail system is configured to move the child car seat along a lateral direction of the passenger seat between at least two seating locations defined by the passenger seat. The rail system is movable independent of the passenger seat to a forward tilted position to allow for movement of the passenger seat between the seated condition and the non-seated condition.

Disclosed is a vehicle rear-seat position adjustment apparatus including a pair of support frames mounted on a floor panel in such a manner as to be spaced apart; a leg frame having a structure where a slot of a predetermined length is formed and fixedly mounted on the support frame; a tilting link of which a front end portion is connected to a slot in the leg frame in a manner that is movable backward and forward; a seat cushion frame of which a front end portion is connected to the leg frame and of which a rear end portion is connected to a rear end portion of the tilting link; a recliner mounted on a side frame connected to a rear end portion of the support frame; and a drive device connected to the front end portion of the tilting link and configured to move the tilting link backward and forward.

A vehicle seat for a motor vehicle includes a seat bottom and a seatback displaceable relative to one another. A seat positioning system has an actuator for displacing one of the seat bottom and the seatback toward the other of the seat bottom and the seatback. The system further includes a position sensor for generating a seat position signal indicative of a position of one of the seat bottom and the seatback relative to the other of the seat bottom and the seatback. The system further includes a controller for generating an activation signal in response to the controller determining that the position is above the position threshold. The actuator displaces one of the seat bottom and the seatback toward the other of the seat bottom and the seatback in response to the actuator receiving the activation signal from the controller.

A position controlling device controls the position of a loading platform. The loading platform includes a loading portion, a base portion, and a coupling portion. The base portion is provided below the loading portion in a manner of supporting the loading portion. The coupling portion couples the base portion and the loading portion with a restoring member between them. One of the upper part of the base portion and the lower part of the loading portion includes a spherical surface that is convex downward. The other one of the upper part of the base portion and the lower part of the loading portion includes a guide portion. The guide portion guides the base portion and the loading portion such that the base portion and the loading portion are movable relative to each other in a direction along the spherical surface.
