A lumbar support apparatus for a vehicle seat includes: a seatback frame having an adjustable inclination angle; an operating mechanism disposed at an upper portion of the seatback frame, the operating mechanism including a connector generating an operating force in a vertical direction by being in contact with a fixture fixed to a vehicle body when the inclination angle of the seatback frame is adjusted; and a support mechanism disposed at a lower portion of the seatback frame, connected to the connector, receiving the operating force generated from the connecting mechanism, and configured to slide in a front and rear direction depending on an application direction of the operating force, such that when the inclination angle of the seatback frame is adjusted to be directed rearward, the support mechanism receives the operating force of the operating mechanism and is advanced forward to support a waist of an occupant.

An operation device (1) includes first bases (81A, 81B) and/or second bases (72A, 72B) that are elastically deformable in the direction of a pivot axis (X1) so that a shaft (120) can be inserted into a shaft hole (110). A first protrusion (121) is formed on a distal end portion of the shaft and projects radially outward from an outer sliding surface (120E). The first bases (81A, 81B) include a first escape section (111) recessed radially outward from an inner sliding surface (110E). The first escape section allows the first protrusion to pass through the first base when the shaft is being inserted into the shaft hole with an operation member (80) located in an initial position. A first slip-off preventing section (113) circumferentially adjacent to the first escape section prevents the shaft from coming out of the shaft hole when the operation member is pivoted from the initial position to an end position.

A motor vehicle latch, in particular, a backrest latch on a motor vehicle seat. This latch is fitted with a locking mechanism consisting essentially of a catch, of a comfort pawl that secures the catch, as well as a pawl that acts on the comfort pawl. The pawl and the catch are resiliently coupled with the aid of at least one spring. The pawl is fitted with a securing arm and an actuating arm spaced apart from the securing arm over a predefined rotation angle, in each case for the comfort pawl.

A striker applied to a vehicle seat includes an engagement pin having a bar shape and a mounting bracket. The mounting bracket includes: a covering portion that covers a part of a lateral surface of the engagement pin from outside and to which one end portion of the engagement pin along a longitudinal axis of the engagement pin is fixed; and a mounting portion that is mounted to a vehicle seat or a vehicle. When directions perpendicular to the longitudinal axis of the engagement pin are regarded as first directions and directions approximately corresponding to seat front-rear directions are regarded as second directions in a state where the mounting portion is mounted, the covering portion is provided with a first load receiving portion that is approximately perpendicular to the first directions and a second load receiving portion that is approximately perpendicular to the second directions.

A latch actuator comprises a motor, a speed reduction gearing coupled to an output shaft of the motor, a spindle, and a motion conversion mechanism. The spindle has a threaded portion in engagement with the speed reduction gearing. The spindle is supported to be rotatable about an axis. The threaded portion is rotationally fixed relative to the spindle. The motion conversion mechanism is configured to cause a displacement of the spindle along the axis when the spindle rotates.

A vehicle lock device includes a base member, a latch, and a release lever. The base member includes a base groove, into which a striker is inserted. The latch includes a latch groove into which the striker is inserted. The latch is pivotal between a lock position, where the striker is fixed to the base groove, and an unlock position, where the striker is released from the base groove. The release lever is pivotal between a lock release position, where pivoting of the latch is permitted from the lock position to the unlock position, and a restriction position, where pivoting of the latch is restricted from the lock position to the unlock position. The release lever includes an engagement release member that contacts the latch when pivoted from the restriction position to the lock release position to pivot the latch from the lock position to the unlock position.

A seat lock device includes: a striker installed in a vehicle body; and a lock unit provided on a seat back tiltable in a seat front-rear direction and holding the seat back in a standing state by locking the striker. The striker includes a base bracket attached to the vehicle body and a U-shaped rod locked by the lock unit, the base bracket has two support portions which respectively support end portions of the rod with a space therebetween in the seat front-rear direction, and at least one of the support portions deforms when a load exceeding a predetermined load is input to the rod so as to permit movement of the end portion of the rod supported by the support portion with respect to the base bracket.

A vehicle seat assembly includes a seatback rotationally coupled to a base at a first pivot. A securing pin is coupled with the seatback. An inertial latch is operable about a second pivot to define an idle position defined by the inertial latch biased distal from the securing pin. A deployed position is defined by an opposing directional force biasing the inertial latch into selective engagement with the securing pin wherein the seatback is maintained in a predetermined rotational position.

A vehicle includes a passenger compartment having a rear wall, a first side wall, a second side wall and a floor. The vehicle further includes a seat having a seat back adjacent a rear wall of the passenger compartment. A storage volume is positioned between the seat, the rear wall, the first side wall and a second side wall and the floor. A securing mechanism selectively locks the seat back to the rear wall.

A seating system for a vehicle having a vehicle body includes a seat bottom and a seat back. The seat bottom includes first and second attachments to the vehicle body, where the first attachment has a locked position for securing the seat bottom to the vehicle body and an unlocked position for facilitating detachment of the seat bottom from the vehicle body. The seat bottom is slidingly attachable to and detachable from the vehicle body at the second attachment when the first attachment is in the unlocked position. The seat back pivotably connected to and slidingly attachable to and detachable from the seat bottom.
