Safety headrest for a motor vehicle
First Claim
1. A safety arrangement for a motor vehicle seat, the safety arrangement comprising a head-rest, means to mount the head-rest for pivotal movement about a first predetermined horizontal axis adjacent the support part of a back-rest of the seat, and depending means adapted to extend downwardly within the back-rest of the seat beneath the first predetermined axis, and which carry a pressure plate to be located within the back-rest at a position behind a torso of an occupant of the seat, so that pressure applied to the pressure plate will cause the head-rest to move, characterized by the rear of the back-rest having a rigid panel and the pressure plate being pivotally connected to the depending means such that continuing pressure applied to the pressure plate after the pressure plate strikes the rigid panel causes the pressure plate to pivot relative to the depending means.

Abstract
A vehicle seat (1) as a head-rest (5) which is mounted for movement about a horizontal axis defined by a bar (7) depending arms (12) extend downwardly into the back of the seat and carry a pressure plate (13) at a position behind the torso of the occupant of the seat so that pressure applied to the pressure plate (13) will cause the head-rest (5) to move forwardly. The pressure plate (13) is pivotally connected (14, 15, 16, 17) to the arms (12) to enable the arrangement to pivot to the maximum extent in a situation where the rear part of the seat is rigid, for example if the seat is a rear seat in a motor vehicle.

10. A safety arrangement for a motor vehicle, the safety arrangement comprising:
-
a head-rest; a substantially horizontal bar rotatably mountable in an upper part of a back-rest of a seat, the head-rest mounted to the substantially horizontal bar such that the head-rest can be pivotally moved about the substantially horizontal bar; at least one depending arm extending downwardly from the substantially horizontal bar, the at least one depending arm capable of being positioned within the back-rest of the seat; and a pressure plate for placement behind a torso of an occupant of the seat, characterized by the at least one depending arm being pivotally connected to the pressure plate such that pressure applied to the pressure plate will cause the head-rest to move, and the rear of the back-rest having a rigid panel such that continuing pressure applied to the pressure plate after the pressure plate strikes the rigid panel causes the pressure plate to pivot relative to the at least one depending arm. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
