Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
89 words
An installation for the adjustment in inclination and height of a seat supported on at least one shaft means by a manually actuatable means, characterized in that the shaft means is supported in two side wall means secured at the seat and is provided with cranked portions which engage in support means forming rows of teeth a-rangee mutually offset to one another with respective to their height, and two tooth rows each serving alternately as bearing support for the associated cranked portions during a rotation of the shaft means.
Claim 2
Dependent Claim
89 words
An installation for the adjustment in inclination and height of a seat supported on at least one shaft means by a manually actuatable means, characterized in that the shaft means is supported in two side wall means secured at the seat and is provided with cranked portions which engage in support means forming rows of teeth a-rangee mutually offset to one another with respective to their height, and two tooth rows each serving alternately as bearing support for the associated cranked portions during a rotation of the shaft means.
Claim 3
Dependent Claim
19 words
An installation according to claim 1, characterized in that the cranked portions are disposed adjacent the side wall means.
Claim 4
Dependent Claim
22 words
An installation according to claim 1, characterized in that the tooth rows are arranged in at least approximately vertically extending column means.
Claim 5
Dependent Claim
38 words
An installation according to claim 3, characterized in that two shaft means are provided which are respectively supported forwardly and rearwardly, as viewed in the vehicle driving direction, in a corresponding side wall means and associated column means.
Claim 6
Dependent Claim
18 words
An installation according to claim 4, characterized in that each shaft means is provided with a hand wheel.
Claim 7
Dependent Claim
75 words
An installation according to claim 5, characteRized in that a spring engages, on the one hand, at a shaft means, and, on the other, at one of the two parts consisting of the seat and the other shaft means and thus causes engagement of the cranked shaft portions in tooth gaps of the tooth rows whereby one shaft means is guided in an elongated aperture extending at least approximately horizontally in the side wall means.
Claim 8
Dependent Claim
87 words
An installation according to claim 6, characterized in that each column means includes leg portions extending parallel to the side wall means, which are provided with slots and with tooth gaps receiving the cranked shaft portions, the gaps starting from the slots and being directed toward one another, and the slots having a width that just permits the passage of a cranked shaft portion during the rotation of the shaft which at the same time is supported with the other cranked portion in the adjacent tooth gap.
Claim 9
Dependent Claim
33 words
An installation according to claim 7, characterized in that the shaft section, with which the shaft is supported in the side wall means, is non-rotatably connected with a bearing means of synthetic material.
Claim 10
Dependent Claim
34 words
An installation according to claim 8, characterized in that the bearing means is so constructed that it abuts with an abutment surface thereof at an extension of a leg portion of the column means.
Claim 11
Dependent Claim
30 words
An installation according to claim 9, characterized in that the extension is formed by a bent portion of a leg of the column means which is substantially U-shaped in cross-section.
Claim 12
Dependent Claim

An installation according to claim 10, characterized in that the cranked portions are disposed adjacent the side wall means.
Claim 13
Dependent Claim
75 words
An installation according to claim 1, characterized in that a spring engages, on the one hand, at a shaft means and, on the other, at one of the two parts consisting of the seat and the other shaft means and thus causes engagement of the cranked shaft portions in tooth gaps of the tooth rows whereby one shaft means is guided in an elongated aperture extending at least approximately horizontally in the side wall means.
Claim 14
Dependent Claim
87 words
An installation according to claim 3, characterized in that each column means includes leg portions extending parallel to the side wall means, which are provided with slots and with tooth gaps receiving the cranked shaft portions, the gaps starting from the slots and being directed toward one another, and the slots having a width that just permits the passage of a cranked shaft portion during the rotation of the shaft which at the same time is supported with the other cranked portion in the adjacent tooth gap.
Claim 15
Dependent Claim
33 words
An installation according to claim 1, characterized in that the shaft section, with which the shaft is supported in the side wall means, is non-rotatably connected with a bearing means of synthetic material.
Claim 16
Dependent Claim
34 words
An installation according to claim 14, characterized in that the bearing means is so constructed that it abuts with an abutment surface thereof at an extension of a leg portion of a column means.
Claim 17
Dependent Claim
31 words
An installation according to claim 15, characterized in that the extension is formed by a bent portion of a leg of the column means which is substantially U-shaped in cross section.
