Abstract
Abstract A movable arm rest, the position of which is adjustable by a motor, and which can be used in particular between the two front seats of a motor vehicle. The arm rest comprises a movable component (1), the upper upholstered part (2) of which serves as a support for the user. By virtue of a motor which is fixed with respect to a support plate (5) disposed at the base of the movable component, the arm rest is displaced along inclined guide ramps which are fixed with respect to a fixed frame (4). The drive is provided by way of pinions (16) meshing with racks (47).

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
192 words
A movable arm rest positioned adjacent at least one seat of a vehicle, comprising: a fixed frame stationarily positioned in a vehicle adjacent a seat and independently of the seat thereof; a movable component having an upper part forming an arm support surface; means for mounting said movable component on said fixed frame for movement independent of said seat between an up position in which said support surface is positioned to support an arm of an occupant of the seat, and a down position in which said support surface is retracted downward with respect to the up position, wherein said means for mounting comprise: (a) support means mounted to said movable component, and (b) guide means in said fixed frame, said guide means being inclined with respect to the horizontal direction and said guide means guiding said support means during movement of said movable component between said up and down positions; and motor means fixed with respect to the movable component for continuously moving said movable component between said up and down positions, whereby said arm rest may be adjusted to a use position between said up position and said down position.
Claim 2
Dependent Claim
192 words
A movable arm rest positioned adjacent at least one seat of a vehicle, comprising: a fixed frame stationarily positioned in a vehicle adjacent a seat and independently of the seat thereof; a movable component having an upper part forming an arm support surface; means for mounting said movable component on said fixed frame for movement independent of said seat between an up position in which said support surface is positioned to support an arm of an occupant of the seat, and a down position in which said support surface is retracted downward with respect to the up position, wherein said means for mounting comprise: (a) support means mounted to said movable component, and (b) guide means in said fixed frame, said guide means being inclined with respect to the horizontal direction and said guide means guiding said support means during movement of said movable component between said up and down positions; and motor means fixed with respect to the movable component for continuously moving said movable component between said up and down positions, whereby said arm rest may be adjusted to a use position between said up position and said down position.
Claim 3
Dependent Claim
61 words
