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.

Foldable headrest spring compensator

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.

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.

A headrest for a vehicle seat has a head support and a mounting assembly carrying the head support on a vehicle seat and comprising a four-pivot linkage having an upper holding element on the head support and a lower holding element fixed to the seat. First and second links interconnect the upper holding element at respective first and second upper pivots on the upper holding element and the lower holding element at respective first and second lower pivots on the lower holding element. Thus the four-pivot linkage can shift the head support relative to the vehicle seat between a front position moved forward toward the head of a seat occupant, and a rear position moved backward therefrom. The upper are at a different relative horizontal spacing on the upper holding element than the lower pivots on the lower holding element.
