The vehicle seat includes: a seat cushion; a seat back; a lifter link mechanism wherein the seat cushion is displaced by a sector gear being displaced; and a speed reducer-equipped motor including a pinion gear engaging with the sector gear; and a first and second restriction portions that stop the rotation of the pinion gear to one side. The sector gear is displaced to one side by the pinion gear being rotated to one side. The displacement of the sector gear to one side is stopped by the rotation of the pinion gear to one side being stopped by the first and second restriction portions. The sector gear is displaced to the other side by the pinion gear being rotated to the other side. The rotation of the pinion gear to the other side is stopped by the displacement of the sector gear to the other side being restricted.

An adjustment assembly for a motor vehicle seat, comprising an adjustment mechanism and a flange that is part of a seat frame, the adjustment mechanism comprising: a housing, itself comprising a bottom and a cover, an output member having a base, an end opposite the base, and a pinion between the base and the end, the pinion being mounted to pivot about an axis of rotation, a backplate, comprising a base plate fixed to the flange and an upper part intended to partially receive the output member, a pumping mechanism housed in the housing and configured to drive the pinion in rotation, the output member being in contact in the flange and in the upper part, the flange and the upper part allowing rotation of the output member about the axis of rotation.

A suspension mat for a vehicle seat comprises a spring element, and a guiding support for at least one electrical cable. The guiding support is molded onto the spring element.

A system for a vehicle with a drive assistance system for an automatic drive includes an adjustment module for an electric seat setting of a driver seat and a control module that is designed such that, during an automatic drive operation of the vehicle, a seat setting of the vehicle seat is kept in a range which is suitable for allowing the driver to assume guidance of the vehicle.

To reduce a whirling movement and abnormal noise of an output gear part. An input-side shaft part 132 and an output gear part 131 which compose a rotating operation member 130 are integrally formed. Owing to this configuration, a bearing of a feed mechanism is integrated with the output gear part, leading to a reduction in a whirling movement of the output gear part due to axial misalignment. A stepped surface 131a formed on an outer periphery of the rotating operation member 130 is stacked on an outer surface 212a of a peripheral edge part of a gear-part through-hole 212 of an attachment bracket 210, and an elastic member 230 is provided between an inner surface 212b of the peripheral edge part of the gear-part through-hole 212 and a brake mechanism 120. This also reduces a whirling movement of the output gear part 131.

A vehicle seat may have adjustment kinematics and a drive device for driving the adjustment kinematics. The adjustment kinematics may have at least one movable rocker and a transverse tube which is mounted rotatably about an axis of rotation. An end region of the rocker may be connected to the transverse tube for rotation therewith. A toothed segment which is curved about the axis of rotation may be connected to the transverse tube for rotation therewith, and, in order to drive the adjustment kinematics, the toothed segment is rotatable about the axis of rotation by the drive device.

Disclosed herein are a method for controlling the posture of a passenger of an autonomous vehicle and an apparatus using the same. The method, performed by the apparatus, includes estimating the current state of the autonomous vehicle using multiple types of sensors installed in the autonomous vehicle, measuring the posture and the eye gaze of the passenger riding in the autonomous vehicle, estimating the next control information of the autonomous vehicle based on the autonomous operation information and the current state of the autonomous vehicle, detecting the optimal posture of the passenger in consideration of the next control information and of the posture and the eye gaze of the passenger, and controlling a seat such that the passenger matches the optimal posture.

An apparatus for adjusting lying posture in vehicle seats is connected between a lower side of a height adjusting mechanism of the seat and upper sides of upper sliding rails of the seat and comprises an upper fixed bracket, a front end execution mechanism, a front end supporting and driving mechanism and a rear end bracket assembly. The upper fixed bracket is provided with a front end fixed supporting rod, a left end and a right end of which are connected with a left fixed supporting rod and a right fixed supporting rod respectively; inner sides of the left fixed supporting rod and the right fixed supporting rod are connected with a left fixed bracket and a right fixed bracket respectively; and a connecting hole is formed in each of front parts and rear parts of the left fixed supporting rod and the right front end fixed supporting rod.
