A headrest for vehicles, especially motor vehicles, is disclosed which comprises a hollow upholstery support mounted for limited pivotal movement on a holder comprising two shanks secured to a vehicle backrest. Stop elements for limiting the pivotal movement are provided for each shank of the holder and abut against the front wall of the support on opposite sides of the pivotal axis of the support. The upholstery support in one embodiment comprises a pair of shells or front and rear support elements made of plastic and having different strength characteristics. The front support element is designed to absorb the forces of the stop elements and the rear support element is designed to be deformable to provide improved safety for passengers seated behind the headrest.

A headrest of the type inclinable fore-and-aft with respect to a headrest stay upon a seat, which includes a trim cover assembly having an opening formed at one side thereof, and includes an inclination mechanism connected to the headrest stay within the trim cover assembly. In forming the headrest, an inner sealing enclosure element is provided in the interior of trim cover assembly to accommodate those inclination mechanism and headrest stay therein, with a free part of the headrest stay projecting outwardly through a hole of the inner sealing enclosure element, while one the other hand, an outer sealing element is securely engaged with that inner sealing enclosure element so as to close both opening of the trim cover assembly and hole of the inner sealing enclosure element. This closing and sealing effect is made positive by a particular male and female sealing engagement arrangement defined between the inner sealing enclosure element and outer sealing element. A method for executing such process is provided to attain a sealed structure of headrest which prevents a liquid base foaming material against leakage therefrom during a foaming step.

A headrest with a decorative board attached to its rear side. The decorative board is formed with a gripping hook member in its inner wall, and on the other hand, the body of headrest is at its rear surface formed with a cut-away area through which is exposed a part of securing rod embedded in the headrest body. The gripping hook member is snap fitted over such exposed part of securing rod in the headrest body, whereby the decorative board is firmly attached to the rear side of the headrest at a given position precisely.

A head and neck rest for vehicle seats comprises a head piece secured to a supporting rod which is mounted by the intermediary of an articulated joint on a saddle member on the back rest of a seat. The joint allows a backwards tilting movement of the supporting rod to which is secured the head piece. Movable and stationary axially aligned joint members are axially traversed by a clamping rod for exerting a predetermined clamping force on the movable member of the joint by the stationary members and causing the movable joint member carrying the head piece to resist a tilting movement due to the action of a shock received by the head or neck of a passenger using the seat of a vehicle.

A detachable headrest (10) for removable installation on a seat back (12) includes a frame (16) having a base member (18) for contacting the seat back and a collapsible, resilient upper member (20) projecting upwardly from the base member above the seat back. A cushion (22) is mounted on and supported by the upper member of the frame. Channel brackets (25) are secured to the underside of the base member and grip the top of the seat back. A flap (46) of fabric extends downwardly from the anterior face of the cushion and covers a portion the seat back so that a person leaning against the flap secures the detachable headrest in position.
