A headrest, especially for the seats in motor vehicles, in which the headrest is adjustable in its inclination against a constantly acting friction force; the adjustment is preferably stepless.
A bearing support for a headrest in a motor vehicle which is pivotal within certain limits after overcoming a constantly effective friction force; a bearing socket which is rigidly connected with the lower area of the headrest member has an essentially triangularly shaped cross section and receives a bearing bolt that is being pressed by a wall subject to an elastic prestress against the remaining walls of the bearing socket.
The invention relates to a device for setting elements which are pivotable relative to each other, especially for setting the pivotable upholstery support of a headrest for vehicle seats, having at least two elements which are not movable in the direction of the axis of rotation which are movable relative to each other about the axis of rotation and at least one setting member which form-fittingly locks these elements in the desired rotational position.
A head-rest is disclosed in which the lower ends of the stays are fixed to a seat frame of a seat back and a head-rest body is mounted to these stays in a manner that it is free to move in a vertical direction so as to provide a deeper recessed cavity in the rear of the seat back.
A head rest adjusting device using a friction mechanism, which permits the forward and backward rotative adjustment of the head rest relative to a head rest stay. The friction mechanism comprises a substantially U-shaped leaf spring receiving the head rest stay therein, and a protruding resilient section is formed on the folded area of the leaf spring so as to give an additional resiliency to the leaf spring per se and thus provide a stable proper friction against the rotation of the head rest about the stay.
The present base for a drawing or drafting board or the like supports the board so that the latter is adjustable in the three directions of space. After each adjustment the board may be locked in the adjusted position by a respective safety or locking device. These safety or locking devices are so arranged and constructed that a yielding is provided in response to the reaching of a load limit applied to the drawing or drafting board whereby damage to the board and its supporting structure is avoided.
