Headrest for a vehicle seat
First Claim
1. Headrest for a vehicle seat with a supporting loop that has two parallel mounting rods for insertion into guide sleeves in the seat, with a head cushion mounted so that it can pivot on the supporting loop about a pivot axis located in an upper portion of the head rest with respect to a seat bottom, said cushion having a cushion support and upholstery fitted over the latter, and with an adjusting device operable in response to collision induced inertial forces to pivotally displace the head cushion relative to the supporting loop whereby the head cushion is moved forwardly for directly abutting a seat occupant in a nape of the neck and the back of the head,wherein the adjusting device is operably connected between the headrest and the seat and includes a manually operated member for accommodating changing pivotal adjustment of the head cushion to respective comfortable seat occupant head supporting positions during normal driving.

Abstract
A headrest for a vehicle seat is provided with a supporting loop and a head cushion mounted thereon and pivotable in a direction of a seat bottom. An adjusting device activated in the event of a collision is provided for displacing the head cushion relative to the supporting loop in such fashion that the head cushion directly abuts the nape of the neck and the back of the seat occupant'"'"'s head. To improve head support comfort by provision for individual adjustment of the head support contour to the needs of the seat occupant when asleep, the adjusting device is additionally equipped with a manual operating member that permits changing the setting of the head cushion without adversely affecting the protective function of the head cushion in the event of a collision.

19. A vehicle headrest assembly comprising:
-
a pivotally mounted cushion support which in use is forwardly disposed behind a vehicle occupant'"'"'s head for supporting said head during normal driving operations and pivots about a pivot axis located on an upper portion of the headrest, cushioning upholstery fitted over the cushion support, a collision responsive adjusting device for automatically pivotally moving the cushion support to a position where the cushioning upholstery is more closely adjacent a head and nape of a neck of a seat occupant in response to collision induced inertial forces, and a manually operable operating member engageable with an adjusting support and operably connected to the headrest for selectively changing the pivotal position of the cushion support and cushioning upholstery for improving occupant head support comfort during normal driving operations, whereby the adjusting support provided for the event of a collision and operably connected to the headrest is also used for selective adjustment of the position of the cushion upholstery. - View Dependent Claims (20, 21)

22. A vehicle headrest assembly comprising:
-
a cushion support with cushioning upholstery fitted thereover which in use is forwardly disposed behind a vehicle occupant'"'"'s head for supporting said head during normal driving operations, pivotal mounting means located on an upper portion of the headrest for accommodating pivotal movement of the cushion support about a pivot axis, collision responsive adjusting support means for automatically pivoting the cushion support toward a position where the cushioning upholstery is moved to a position further supporting a nape of the neck and back of the head of an occupant in response to rear end collision induced inertial forces, and manually operable adjusting means engageable with the adjusting support means and operably connected to the headrest to accommodate selective occupant adjustment of the pivotal position of the cushion support for improving occupant head cushion support during normal driving operations without adversely affecting operation of the collision response adjusting support means.
