摘要： An armrest has a base element, an arm-support element movable in a direction on the base element between a pair of end positions, a mount fixed on one of the elements and formed with a throughgoing hole extending in the direction, and a rod fixed on the other of the elements and extending along an axis with play through the hole of the mount. A pair of inelastic slide-bearing rings fixed in the hole at ends thereof loosely surrounds the rod. A respective elastic bearing block fixed in and relative to each of the rings presses the rod radially against a diametrally opposite inner-surface portion of the respective ring.

摘要： An armrest has a base, an arm support pivotal on the base about a pivot axis in opposite pivot directions between a first position and a second position, and a latch for locking the arm support pivotally relative to the base in at least one pivot position. The latch has a movable first formation and an immovable second formation that can be releasably engaged with the first formation. The first formation is movable between a locked position and a released position and is urged by a spring or the like into the locked position. The armrest is mounted on a seat, for example, and in particular a vehicle seat.

摘要： An improvement to foldable headrests remote actuators by providing a tube mounted spring compensator to facilitate movement between a stowage position and an operating position. The spring compensator is inserted concentrically within the hollow tubes that support the adjustable headrests to boost or compensate for the lack of force routinely experienced under cold weather use or aging of materials. The spring compensator is positioned inside the headrest support tube to help pull the cable up through the seat when the seat and headrest are returned from a stowage position to a passenger seating position. The spring compensator inside the headrest support tube allows the use of a smaller torsion spring in the headrest and reduces the stress on the components in the mechanism.

摘要： The invention relates to a headrest for a seat, in particular for a vehicle seat, comprising a head support (11) that can be supported on a vehicle seat by a mounting assembly (13), wherein the mounting assembly (13) comprises a linkage (18) comprising a first holding element (16) on the head support (11), and a second holding element (17) fixed to the seat part, that the first holding element (16) and the second holding element (17) are connected to one another by guides (19a, 19b, 20a, 20b) in such a way that at least one four-pivot linkage (27a, 27b) is formed that can shift the head support (13) relative to the vehicle seat between a front position moved forward toward the head of a seat occupant, and a rear position moved backward.

摘要： The invention relates to a motor-vehicle accessory, comprising a first part and at least one second part pivotal about an axis (a) relative to the first part in at least one bearing assembly (20a, 20b), and the bearing assembly (20a, 20b) comprises a bearing pin (14) on which a bearing sleeve (22) is coaxial to the bearing axis (a), and the bearing pin (14) forms a head (19) with an axial retaining face (30).The particularity is that of the bearing pin (14) having first coupling formation that engages in a second coupling formation of the bearing sleeve (22) and prevents relative rotation in a pivot direction (u1, u2) between the bearing sleeve (22) and the bearing pin (14).
