Abstract
Abstract A head restraint for a vehicle, which in its stowage position is received by a hollow in the rear window shelf of the vehicle and which can be transferred, together with its bearing arms, into an operational position near to the backrest, the bearing arms being supported on the vehicle side on an inside wall of the hollow, so that, in the stowage position, both the head restraint and its bearing arms rest in the hollow. Before, during or after a swinging operation, the head restraint is pivoted in the opposite direction to the swing of the bearing arms, so that employment in a confined space is possible.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
A head restraint apparatus for a vehicle, wherein a head restraint is supported by means of at least one bearing arm engaging a solid part of the vehicle and which, together with the at least one bearing arm, can be transferred from an in-use position into a stowage position in which the head restraint is received by a hollow member in the rear window shelf, comprising an inside wall means of the hollow member serving as a solid part of the vehicle for supporting the at least one bearing arm, and means for pivoting the head restraint before, during or after conclusion of a swinging operation, in the opposite direction to the swing of the at least one bearing arm.
Claim 2
Dependent Claim
120 words
A head restraint apparatus for a vehicle, wherein a head restraint is supported by means of at least one bearing arm engaging a solid part of the vehicle and which, together with the at least one bearing arm, can be transferred from an in-use position into a stowage position in which the head restraint is received by a hollow member in the rear window shelf, comprising an inside wall means of the hollow member serving as a solid part of the vehicle for supporting the at least one bearing arm, and means for pivoting the head restraint before, during or after conclusion of a swinging operation, in the opposite direction to the swing of the at least one bearing arm.
Claim 3
Dependent Claim
22 words
