A vehicle seat includes a lower member, a frame member, and a link member connected to the lower member and the frame member. The link member includes a first circular hole portion connected to the lower member so as to pivot about an axis in a width direction of a vehicle, a second circular hole portion connected to the frame member, a main body of plate shape in which the first circular hole portion and the second circular hole portion are formed, a flange projecting from the main body in a direction crossing the main body, a recess formed to bring the flange closer to an imaginary straight line connecting a center of the first circular hole portion with a center of the second circular hole portion, and an offset portion formed to shift the main body in a thickness direction of the main body.

In a method for locking an adjustment device of a motor vehicle seat, a usage situation and/or danger situation is detected. In response to the detected usage situation and/or danger situation, a locking action for the adjustment device is selected, and the selected locking action for the adjustment device is executed.

A child safety seat includes a seat shell, a headrest and a side protection part. The seat shell has a seat portion, a backrest portion and a sidewall, the sidewall protruding forward from the backrest portion. The headrest is connected with the backrest portion and is movable along the backrest portion, the headrest having a side support portion protruding forward. The side protection part is disposed adjacent to the sidewall at an inner side thereof, the side protection part extending along the inner side of the sidewall from a location adjacent to the seat portion toward a top of the backrest portion, a portion of the side protection part being located between the sidewall and the side support portion of the headrest.

Provided is a conveyance seat that effectively reduces a load to be applied to an occupant at the time of a vehicle collision. A conveyance seat includes a seat back and a headrest. The seat back includes a chest support member inside the seat back, which receives a chest of an occupant to support the chest of the occupant when a backward movement load is applied to the occupant because of a vehicle collision. The headrest includes a head support member inside the headrest, which receives a head of the occupant to support the head of the occupant when the backward movement load is applied to the occupant. When the backward movement load is applied to the occupant, both the chest support member and the head support member receive the backward movement load.

An anti-submarine arrangement for a vehicle seat includes an elongated member pivotably attached between opposing members of a seat bottom support structure. A leg is fixedly attached to the elongated member and pivotably attached to a structural portion of the vehicle seat. The elongated member is rotatable forward and downward relative to the structural portion of the vehicle seat. A damper arrangement is attached to the leg and to the structural portion of the vehicle seat. The damper arrangement opposes a forward and downward rotation of the elongated member.

A seat backrest includes right and left side frame segments, a pressure receiving member disposed between the side frame segments movably in a front-back direction, and a cushion pad covering the front of the side frame segments and pressure receiving member. The pressure receiving member includes a main body part, and extending parts extending laterally from both sides of the main body part. The cushion pad includes a back receiving part covering the front of the main body part, and bank parts disposed on both sides of the back receiving part, protruding forward from both sides, and covering the front of the extending parts and side frame segments. A recess is formed at an area, facing a corresponding extending part of the extending parts, of a rear surface of each bank part.

A vehicle seat arrangement has a vehicle seat for attaching to a vehicle structure of a vehicle, in particular a motor vehicle, with a lower seat part having a seat structure and with a seat back. The lower seat part is mounted or can be mounted in a longitudinally displaceable manner on the vehicle structure by a seat console, wherein at least the seat back is adjustable from a sitting position into a resting or lying position, and wherein between the lower seat part and the vehicle structure an energy absorption device is provided. In the event of a collision of the vehicle with an obstacle, the energy absorption device permits a braked relative movement along a braking path between the vehicle seat, which persists in a forwards movement due to inertia, and the vehicle structure, which is braked due to the collision. In the normal state, the vehicle seat is locked relative to the vehicle structure by a locking device and the locking is released in the event of a collision. The locking device is designed such that the locking is released and the longitudinal displaceability of the vehicle seat is enabled before the mass-induced forces of inertia of the body of a person lying on the vehicle seat are completely supported on the seat structure of the lower seat part, and therefore the body only enters into force-transmitting contact with the seat structure when the vehicle seat is already moving forwards relative to the vehicle structure.

A vehicle seat assembly is provided with a seatback frame adapted to be mounted to a vehicle interior. The seatback frame has a front region facing a forward direction, and a rear region. A first bracket is mounted to the front region of the seatback frame. A second bracket is mounted to the first bracket and the rear region of the seatback frame. At least one head restraint post is mounted to the first bracket or the second bracket and spaced apart from the seatback frame so that upon a rear vehicle impact, the second bracket deforms as the at least one head restraint post is translated toward the seatback frame.

A passenger□s weight measurement device for a vehicle seat includes an upper rail provided on a lower rail that is fixable to a vehicle floor, the upper rail being movable in at least one of rear and front directions; a load sensor fixed onto the upper rail; and a frame provided on the load sensor and below the vehicle seat. In plan view, the load sensor protrudes from the frame in at least one of left and right directions.

A seating system for at least one occupant in a vehicle interior is disclosed. The seating system may provide a seat assembly with a base assembly configured to be mounted in the vehicle interior and a seat structure configured to be coupled to the base assembly and providing a seat configured for movement relative to the base assembly. Movement of the seat relative to the base assembly may be made by at least two of recline movement or swivel movement or tilt movement. Recline movement may be generally translating movement of the seat structure. Swivel movement may be rotational movement of the seat structure. Tilt movement may be generally translating movement of the seat structure transverse to recline movement. The base assembly may be a mechanism configured to facilitate movement of the seat structure relative to the base assembly.
