The object of the invention is to provide a vehicle seat which can improve degree of freedom in the design of the vehicle seat. A vehicle seat with a seat cushion and a seat back includes: right and left side frames 20 constituting right and left frames of the seat back; a pressure-receiving member 40 disposed between the right and left side frames 20 and configured to receive a load from an occupant; and a driving mechanism 50 disposed at each of right and left sides of the pressure-receiving member 40 and configured to cause a right end portion or a left end portion of the pressure-receiving member 40 to move from an initial position to an advanced position that is located frontward of the initial position or to move from the advanced position to the initial position, wherein the driving mechanism 50 includes a linkage (drive link member 100 and contact link member 200) configured to be connected to the pressure-receiving member 40 and a driving source 52 configured to actuate the linkage, and wherein the linkage is configured to operate when a load equal to or greater than a predetermined amount is input from the occupant to the pressure-receiving member 40 to cause the pressure-receiving member 40 to move to a backward position that is located rearward of the initial position.

A vehicle seat that includes: a cushion; a backrest; an articulation having a first flange fixed to the cushion and a second flange fixed to the backrest, the second flange being mounted so as to be able to rotate with respect to the first flange; a device for straightening the backrest interdependently rotating with the second flange and defining a straightening slot comprising a first portion separated from a second portion by a bridge; and a pin integral with the backrest, extending into the first portion of the straightening slot. When an impact torque greater than a predetermined torque is applied to the backrest, the pin breaches the bridge and then moves freely in the second portion.

An assembly includes a seat bottom. The assembly includes a seatback supported by and movable relative to the seat bottom between an upright position and a reclined position. The assembly includes an actuator supported by the seat bottom and operatively coupled to the seatback to move the seatback from the reclined position to the upright position. The assembly includes a computer having a processor and a memory storing instructions executable by the processor to command to actuator to move the seatback to the upright position in response to detecting a pending vehicle impact.

To reduce the weight of a cross member bridged between right and left sides of a seat frame. A seat frame includes an upper frame forming an upper portion of a seat back frame, and a cross member bridged at the upper frame. The cross member includes right and left end portions in a seat width direction, the right and left end portions being fixed to the upper frame; and a first recessed portion that is recessed upward or downward and provided between the right and left end portions. The first recessed portion is provided at a center portion of the cross member in the seat width direction.

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 occupant protection apparatus includes: a vehicle seat arranged in an inner space of a side wall of a vehicle; a side airbag device provided in the side wall or the vehicle seat and including a side airbag to be inflated and deployed between the side wall and the vehicle seat. The vehicle seat includes: a pressure-receiving portion to receive a load from an occupant seated on the vehicle seat; and a frame to support the pressure-receiving portion. The occupant protection apparatus further comprising an electronic control circuit configured to perform moving the pressure-receiving portion so that the occupant is pushed away from the side wall before the occupant comes into contact with the side airbag at an activation time when the side airbag device is activated by an impact acting on the side wall from an outside of the vehicle and the side airbag is inflated and deployed.

A vehicle seat device capable of suitably restraining an occupant by means of a seat belt device includes a seat main body having a seat cushion and a seat back, a reclining device connecting the seat back to the seat cushion so as to be pivotable and capable of locking a pivoting motion of the seat back, and a seat belt device for restraining an occupant seated on the seat main body. The seat belt device includes a lap belt restraining the occupant's lumbar or thighs, a belt anchor attached at a position beside the seat main body and having a belt engaging portion engaging with an engaged portion provided in a tip portion of the lap belt, and an anchor moving device capable of moving the belt engaging portion of the belt anchor in a seat front to back direction with respect to the seat main body.

An active system and a computer-implemented method for reducing vibrations of seats in a vehicle is described. The system and method adjust a damping and/or a stiffness of a vibration damper based on system input signals from the vehicle or seat system. The signals include one or more of a signal associated with a user weight, a signal associated with time-dependent movement of a vehicle frame, and a signal associated with time-dependent movement of a seat back or a seat pan. The damping or the stiffness are adjusted by a closed loop control.

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 structure includes a vehicle seat including a seat cushion and a seatback, and a pushing apparatus provided inside the seatback at a predetermined height. The pushing apparatus includes a pushing portion that, at a time of a vehicle collision in which an occupant sitting on the vehicle seat moves to a seat forward side, pushes a portion of a seat front face of the seatback to the seat forward side.
