First Claim
Patent Images
1. A safety seat for use in a motor vehicle, the safety seat comprising:
- a squab;
back associated with the squab and a head-rest associated with the back;
a pivotal connection between the back and the squab, the pivotal connection being such that the back will move pivotally rearwardly relative to the squab when subjected to a substantial force; and
means associated with the head-rest for moving the head-rest with a movement that has an upward component and a forward component relative to the back of the seat during at least part of the rearward movement of the back of the seat.

Abstract
A safety seat for use in a motor vehicle has a squab (101) and a back (104) and a head-rest (105). There is a pivotal connection between the back (104) and the squab (101). The head-rest (105) is mounted on a series of levers (112). If the vehicle is involved in a rear impact, the back (104) of the seat may move rearwardly. Simultaneously, because of the levers (112) the head-rest (105) will move forwardly relative to the back of the seat. Thus, the head-rest will come into contact with the head of the occupant of the seat, thus minimizing the risk of “whiplash” injuries.

6. A safety seat for use in a motor vehicle, the safety seat comprising:
- a squab;
a back associated with the squab;
a head-rest associated with the back;
support means pivotally connected to the back for pivotal movement of the back relative to the support means between first and second limits, the support means being pivotally connected to the squab to permit movement of the support means and the back, relative to the squab;
energy-absorbing means for absorbing energy when the support means pivots relative to the squab of the seat; and
a linkage between the head-rest and the support means for causing the head-rest to pivot forwardly, relative to the back of the seat, when the back of the seat executes a pivoting motion relative to the support means and for retaining the head-rest in a substantially fixed position relative to the back seat when the support means and the back together pivot relative to the squab. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
