Abstract
Abstract A vehicle seat, the seat portion of which has an adjustable inclination, is supported on two concave guide rails (as viewed from the seat portion) which are supported by a seat frame and extend in the longitudinal direction of the seat portion so that the seat portion is longitudinally adjustable and can be locked in a selected position by means of a locking device. The locking device is arranged in the central section of the seat portion and includes a straight bar extending in the longitudinal direction of the seat portion. The ends of the bar are connected with the seat frame. This bar supports an adjusting member which can be adjusted steplessly in its longitudinal direction and can be secured in any position against a longitudinal movement. A coupling member is coupled with this adjusting member and is connected on its other end with the seat portion which is longitudinally adjustable on the guide rails.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
171 words
Vehicle seat, the seat portion of which has an adjustable inclination, supported on concave guide rails which are further supported by a seat frame and extend in the longitudinal direction of the seat portion, comprising: means, arranged in a central section of the seat portion, for locking the seat portion in a selected position; a bar means of constant length for carrying the locking means, said bar means extending in the longitudinal direction of the seat portion, the ends of said bar means being connected with the seat frame; an adjusting member which can be moved steplessly in its longitudinal direction and which can be locked in any position against longitudinal movement, said adjusting member being supported by the bar means; and a coupling member, being pivotally connected to the adjusting member on one end and being pivotally connected on another end to a support member for the seat portion, said other end of the coupling member being longitudinally movable on the guide rails; whereby the seat portion is longitudinally adjustable.
Claim 2
Dependent Claim
171 words
Vehicle seat, the seat portion of which has an adjustable inclination, supported on concave guide rails which are further supported by a seat frame and extend in the longitudinal direction of the seat portion, comprising: means, arranged in a central section of the seat portion, for locking the seat portion in a selected position; a bar means of constant length for carrying the locking means, said bar means extending in the longitudinal direction of the seat portion, the ends of said bar means being connected with the seat frame; an adjusting member which can be moved steplessly in its longitudinal direction and which can be locked in any position against longitudinal movement, said adjusting member being supported by the bar means; and a coupling member, being pivotally connected to the adjusting member on one end and being pivotally connected on another end to a support member for the seat portion, said other end of the coupling member being longitudinally movable on the guide rails; whereby the seat portion is longitudinally adjustable.
Claim 3
Dependent Claim
50 words
Vehicle seat according to claim 1, characterized in that: said coupling member is connected by a hinge to the adjusting member and to the support member for the seat portion; and said hinge axes lie at a right angle to longitudinal axes of the guide rails and the bar means.
Claim 4
Dependent Claim
35 words
Vehicle seat according to claim 1, characterized in that: said coupling member includes two adjacent, spaced arms which can be loaded with one of compression and tension, between which arms the adjusting member is located.
Claim 5
Dependent Claim
39 words
Vehicle seat according to claim 1, characterized in that the longitudinal axis of the bar means is at least approximately parallel to the direction of a tangent to a curved path in a central section of the guide rails.
Claim 6
Dependent Claim
55 words
Vehicle seat according to claim 1, further comprising: runner rail means for engaging with the guide rails; and a cross beam means for extending beneath the seat portion; said cross beam means extending from one of the runner rail means to another runner rail means; said coupling member being connected beneath the cross beam means.
Claim 7
Dependent Claim
26 words
Vehicle seat according to claim 1, characterized in that: said adjusting member can be locked in place on the bar means by a releasable clamping device.
Claim 8
Dependent Claim
