A conveyance seat includes a seatback frame disposed in a seatback and supporting an end of a wire member for supporting an occupant in a manner such that the wire member is movable. The seatback frame includes a supporting plane part that the end of the wire member is disposed therein, the supporting plane part being provided along a direction perpendicular to a longitudinal direction of the wire member. A support portion that supports the wire member in a manner such that the wire member is movable is formed in the supporting plane part.

An adjustable seat occupant assembly for a vehicle seat including an elongate beam spring with an inline slider mechanism at its proximal end that displaces an beam spring flexor, e.g., elongate strap or link, operatively connected to a distal end of the spring to change the amount of flexure and prominence during adjustment to adjust support. In one embodiment, the mechanism is an inline slider crank mechanism carried by a drive carriage extending from the proximal end that rotates a crank when a knob is turned reciprocating the flexor between a fully retracted position where flexure is maximum and a fully extended position flexure is minimum. In another preferred embodiment, the mechanism is an inline slider cam-follower mechanism with a cam rotated by the knob to slidably displace a translating follower yoke that moves the flexor to change spring flexure.

A vehicle seat is provided with a seat cushion and a seat back, the seat back includes: left and right side members extending up and down; a lower cross member extending laterally and joined to the left and right side members, a cross member extending laterally above the lower cross member and joined to the left and right side members; at least one wire member extending up and down and joined to the lower cross member and the cross member; and at least one shoulder support member supported on an upper portion of the wire member. The shoulder support member includes: a first plate part facing in a front-rear direction and joined to the upper portion of the wire member; and a second plate part facing in the front-rear direction and connected to the first plate part via a flexible part.

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 seating assembly includes a seatback frame and a seat frame defining a seating frame. A plurality of distinct assembly modules are configured for attachment with the seating frame. The plurality of distinct assembly modules include a back cushion module, a hard back module, a headrest module, and a seat cushion module. The seat cushion module includes a composite cushion pan having a rearward support defining an intermediate open area. A forward support is pivotally coupled to the rearward support. A suspension assembly is disposed in the intermediate open area. A cushion extends over the composite cushion pan. A coverstock covers the cushion.

A vehicle seating assembly includes a seating frame defined by a seatback frame and a seat frame. A plurality of distinct assembly modules are configured for attachment with the seating frame. The plurality of distinct assembly modules include a back cushion module, a hard back module, a seat cushion module, and a headrest module. The back cushion module and hard back module are operably coupled together. The headrest module extends over and operably couples the back cushion module with the seat cushion module to substantially encompass the seating frame. The seat cushion module is positioned on the seat frame in front of the seatback frame. First and second side trim pieces are configured to extend over the seat frame concealing side portions of the seat cushion module.

An apparatus includes a frame configured to interface with a seatback of a vehicle seat, a lumbar mat configured to provide lumbar support for the vehicle seat, and a flexible element coupling the frame to the lumbar mat. Another apparatus includes a lumbar mat configured to interface to a seatback of a vehicle seat, a flexible printed circuit board (PCB) affixed to a rear side of the lumbar mat, and a cover arranged rearward of the lumbar mat and flexible PCB and configured to enclose circuitry of the flexible PCB.

A vehicle seat is provided with a seat cushion and a seat back, the seat back includes: left and right side members extending up and down; a lower cross member extending laterally and joined to the left and right side members, a cross member extending laterally above the lower cross member and joined to the left and right side members; at least one wire member extending up and down and joined to the lower cross member and the cross member; and at least one shoulder support member supported on an upper portion of the wire member. The shoulder support member includes: a first plate part facing in a front-rear direction and joined to the upper portion of the wire member; and a second plate part facing in the front-rear direction and connected to the first plate part via a flexible part.

The vehicle seat structure includes a seat back body that extends in the seat width direction and the seat up and down direction and can support a back portion of the occupant, and a central reaction force applying portion that is provided at a portion where the back portion of the occupant comes into contact with the center portion of the seat back body in the seat width direction and is capable of applying a reaction force to the back portion of the occupant in contact with the seat upper side.

A vehicle seat provided in a vehicle includes: a seat body including a seat cushion and a seatback; an occupant support device displaceably provided on the seat body to press an occupant seated on the seat body; a notification device provided on the seat body to make notification to the occupant; an information acquisition device that acquires information including at least one of a surrounding environment of the vehicle and a driving state of the vehicle; and a control device that controls the occupant support device and the notification device based on the information. The notification device may be provided on the occupant support device. When the vehicle turns, the control device may cause the vibrator disposed on a side opposite from the turning direction to vibrate.
