An angularly and vertically adjustable head rest which is secured to a back rest of a motor vehicle seat. The heat rest may be immobilized in a desired height position by locking mechanism disposed entirely within and surrounded by the foam plastic cushion of the head rest. For height adjustment a first locking mechanism may be released by lateral pressure applied against one edge portion of the head rest and for tilting adjustment a second locking mechanism may be released by pressure applied to the opposite side edge of the head rest.
A head support particularly for use with motor vehicle seats is disclosed. The head support comprises a padded support member which is mounted on a pair of support bars, the later being fixedly secured to the back of the vehicle seat. The padded support comprises a body having a U-shaped cross-section which is adjustably swivellingly connected to the support bars by means of molded connecting bodies which, in turn, are vertically adjustable along the support bars. The connecting bodies and adjusting and swiveling mechanisms are located interiorly of the padded support to provide maximum safety for the vehicle occupants.
A head restraint assembly 10 is disclosed having an adjustable head restraint member 11 which is securable in position between a forward position and a rearward position by a helical coil locking member 14. The locking member 14 is, in a normally relaxed state, of smaller internal diameter than the external diameter of a transverse support rod 24 with which it is engaged. By rotation of one end portion 19 of the locking member 14 with respect to the other end portion 21 the locking member 14 is partially unwound thereby releasing its locking grip on the support rod 24.
An upwardly and downward adjustable headrest assembly for the seat backrest of a vehicle includes a fixed stay upstanding from the seat backrest, guide shoes slidable up and down along the stay and carrying a headrest body, and a locking mechanism disposed between one guide shoe and the stay for locking the guide shoe to the stay at any position therealong. The interior of the headrest provides the space needed to receive the stay as the headrest is moved up and down along the stay via the guide shoes, thereby allowing the headrest assembly to be installed on the backrest without increasing the thickness of the backrest.
Modularly arranged seat frameworks supporting of custom upholstered seat cushions and mountable in a variety of makes, models and years of automboiles. Cable-actuated, spring release means coupled between the backrest and bench frame portions to at least one hinge member facilitate a recliner adjustment of one to the other. Included mounting brackets support a seat belt retractor to the backrest framework with the extreme ends of the belt coupling to the automotive frame.
A convertible motor vehicle with at least one seat having an extendable roll bar incorporated into an upper portion thereof. In one embodiment the roll bar forms part of the headrest of the seat in a retracted rest position and is automatically extended upward from the headrest into a locked, extended operating position. The extended roll bar cooperates with the reinforced framework of the backrest of the seat which is mounted to the vehicle chassis in the conventional manner to provide a sufficient structural member to support a vertically downward impact load on the extended roll bar that occurs when the vehicle rolls over. Known motion sensors are used to trigger the roll bar and cause a release from its rest position to its operating position. In an alternate embodiment of a seat without a headrest, the roll bar forms an upper portion of the backrest of the seat while in its rest position and extends upward into its operating position in the same manner as the headrest embodiment.
