In order to cause no difficulty in an assembling process for assembling a resin plate to a seatback even if a plurality of bosses formed on the resin plate vary somewhat in dimension in a height direction, and also in order to prevent unpleasant noise, a vehicle seat is provided in which the resin plate of the seatback has a plurality of bosses formed thereon in positions facing the seatback frame, and under no load on the resin plate, some of the plurality of bosses are in contact with the seatback frame and the remaining ones of the plurality of bosses are out of contact with the seatback frame. On the other hand, while the resin frame is deformed by application of load in a direction of the seatback frame, the some bosses and the remaining bosses are in contact with the seatback frame to bear the load.

The present disclosure relates to an adjustment device for a vehicle seat comprising adjusters adjustable in relation to one another, where on the first adjuster a toothed rack with an interlocking is hinged, and on the second adjuster a pinion is pivoted, the interlocking engaging with the pinion for adjusting the toothed rack and for moving the two adjusters in relation to one another, where, further, a toothed rack blocking element is affixed to the second adjuster, and the toothed rack, when adjusted, runs between the toothed rack blocking element and the pinion.

A vehicle seat capable of exhibiting both performances of regulating an input of a load and reducing vibration is provided. One aspect of the present disclosure is a vehicle seat including a coupling structure coupling a first member and a second member. The coupling structure includes a bolt inserted through the first member and the second member, an auxiliary member arranged so as to hold the first member between the auxiliary member and the second member in an axial direction of the bolt, a first elastic element arranged between the first member and the second member in the axial direction, the first elastic element being in contact with the first member and the second member, and a second elastic element arranged between the first member and the auxiliary member in the axial direction, the second elastic element being in contact with the first member and the auxiliary member.

A vehicle seat having a drive device for driving a adjustment kinematics of the vehicle seat may have an adjustment arm, and a tensioning device. The drive device may have a pinion which can be rotated about a pinion rotation axis and which is in toothed engagement with a tooth segment of the adjustment arm. The tensioning device pretensions the adjustment arm so that the tooth segment is pretensioned in the direction of the pinion. The tensioning device has at least one sliding element which is in abutment with the adjustment arm. During an actuation of the height adjustment kinematics, the at least one sliding element slides along the adjustment arm. The sliding element is resiliently pretensioned by a resilient element.

A seat support of the conveyance seat includes right and left front foot members that are attached to a body floor with a gap therebetween in a seat width direction and extend to protrude upward from the body floor and a foot linking member that links the upper portions of the right and left front foot members and is disposed to partially overlap the right and left front foot members in the up and down direction. A closed section structure is formed by an opposing wall portion disposed at a position opposing the foot linking member in an up and down direction, right and left side wall portions continuously bent from both end portions of the opposing wall portion in a seat width direction and protruding to abut toward the foot linking member in the front foot member, and the foot linking member.

An article, such as a vehicle seat, includes a one-piece vehicle head restraint structure that defines a frame and a plurality of receptacles. There are metallic resonators disposed in the receptacles. Polymeric dampers line the receptacles and circumscribe the metallic resonators.

A sliding rail transmission device and a vehicle include a driving portion and at least one sliding rail assembly, the sliding rail assembly includes a rail and a movable member, the rail is provided with a flanging which extends downward, the flanging forms a first transmission toothed belt, and the rail is provided with a damping strip at a position of the first transmission toothed belt, the damping strip forms a second transmission toothed belt, the first transmission toothed belt and the second transmission toothed belt are arranged side by side, the movable member is provided with a transmission gear, the transmission gear is arranged below the first transmission toothed belt and the second transmission toothed belt, and the transmission gear can mesh with the first transmission toothed belt and the second transmission toothed belt simultaneously; and the driving portion drives the transmission gear to rotate to drive the movable member to move along the rail. Such arrangement is beneficial to realizing stable driving, and foreign matters are not easy to fall into the first transmission toothed belt and the second transmission toothed belt. The first transmission toothed belt and the second transmission toothed belt are arranged side by side and mesh with the transmission gear together, which not only ensures the overall strength of the transmission toothed belts, but also achieves the object of vibration damping and is beneficial to enhancing the adaption of tolerance.

An arm rest assembly and aircraft passenger seat including the same. The arm rest includes a friction mechanism for resisting abrupt rotational movements of the arm rest. A rotationally fixed frame member defining a rotational axis and receives a rotational member of the arm rest configured to rotate around the rotational axis. A groove formed in an outer circumferential surface of the rotational member seats a O-ring disposed between the groove and an inner circumferential surface of the frame member. Tolerance between the frame member and arm rest is such that the O-ring is held in the groove in a compressed state and frictionally engagement each of the rotational member and the frame member.

A seat support of the conveyance seat includes right and left front foot members that are attached to a body floor with a gap therebetween in a seat width direction and extend to protrude upward from the body floor and a foot linking member that links the upper portions of the right and left front foot members and is disposed to partially overlap the right and left front foot members in the up and down direction. A closed section structure is formed by an opposing wall portion disposed at a position opposing the foot linking member in an up and down direction, right and left side wall portions continuously bent from both end portions of the opposing wall portion in a seat width direction and protruding to abut toward the foot linking member in the front foot member, and the foot linking member.

A longitudinal adjuster for a vehicle seat may have a rail assembly having two rail pairs of seat rails. The respective rail pair has a fixed seat rail and a seat rail that is movable relative to the fixed seat rail. The rail assembly may also have a motor unit and a gearbox unit, which couples the motor unit and the movable seat rail. The rail assembly may also comprise a holder for receiving a gearbox housing of the gearbox unit. The holder is arranged with the gearbox unit in a hollow space formed by the one rail pair and is fixed to the movable seat rail. The holder is formed so as to be open at one end and closed at the opposite end. The holder has at least one stiffening element at the open end.
