Abstract
Abstract An adjustable head rest for a vehicle seat is formed by supporting rod fitted at its upper end into a head rest member and at its lower end into the frame of the vehicle seat. Means are adjustably positionable on the supporting rod for varying the height of the head rest above the seat. For such adjustable positioning a plurality of recesses are formed along the supporting rod. The edge of a hole through which the supporting rod passes is brought into engagement within one of the recesses under the biasing force of a resilient tongue in the retaining member propped against the supporting rod.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
193 words
A head rest assembly for a vehicle seat having a seat frame comprising a head rest member (1), at least one supporting rod (2) secured at its upper end to said head rest member and adapted to extend downwardly with its lower end disposed within said vehicle seat frame, a plurality of recesses (12) formed along one lateral side of said supporting rod in a longitudinally spaced relation, said recesses being substantially wedge-shaped having a first face (12) substantially perpendicular to the axis of the rod and a second face (12'''') extending downwardly at an angle to the first face, a strip-shaped resilient retaining member (13) mounted on said frame and movable for a predetermined distance along said frame in a plane substantially normal to said rod (2) in the lateral direction of said vehicle seat and having a hole with an edge through which said rod passes, a tongue member (18) cut and bent obliquely upwardly towards said rod from said retaining member, said tongue member being propped at the free end thereof against said rod thereby urging the edge of said hole to come into engagement with one of said recesses.
Claim 2
Dependent Claim
193 words
A head rest assembly for a vehicle seat having a seat frame comprising a head rest member (1), at least one supporting rod (2) secured at its upper end to said head rest member and adapted to extend downwardly with its lower end disposed within said vehicle seat frame, a plurality of recesses (12) formed along one lateral side of said supporting rod in a longitudinally spaced relation, said recesses being substantially wedge-shaped having a first face (12) substantially perpendicular to the axis of the rod and a second face (12'''') extending downwardly at an angle to the first face, a strip-shaped resilient retaining member (13) mounted on said frame and movable for a predetermined distance along said frame in a plane substantially normal to said rod (2) in the lateral direction of said vehicle seat and having a hole with an edge through which said rod passes, a tongue member (18) cut and bent obliquely upwardly towards said rod from said retaining member, said tongue member being propped at the free end thereof against said rod thereby urging the edge of said hole to come into engagement with one of said recesses.
Claim 3
Dependent Claim
