DESCRIPTION
DESCRIPTION OF THE INVENTION

The perspective illustration of the operating mechanism in FIG. 1 shows the fastening case 5, the handle housing 6, and the central block 7 located inside the housing.
The central block 7 is mounted to move and pivot on a shaft 8, which in turn is held in the fastening case 5 in its outer case wall. FIG. 2 and FIG. 4 shows this more precisely.
The central block 7 located on the shaft 8 is held in its central position (see FIG. 2) by the two cylinder springs 9 and 10 and can optionally be moved axially on the shaft as illustrated to the right or to the left against the pressure of one of the springs 9 and 10.
The central block is moved axially by means of the handle housing or single handle 6, which is the only operating part or handlepiece that the illustrated operating mechanism has.
The single handle 6 is connected to the central block 7 by the handle housing shaft 11. When the single handle is moved in its long direction, i.e., parallel to the central block shaft 8, then the central block, depending on its direction of motion, operates either the operating element 13 or the operating element 14 by means of its projecting part 12, each of which is mounted on the rear wall of the fastening case 5. The operating elements 13 and 14 in the illustrated example of embodiment control in logical correlation the adjusting unit of the automobile seat that causes the horizontal shifting of the seat horizontally toward the front or toward the rear.
When the single handle 6 in the illustration of FIG. 1 is moved upward or downward, perpendicular to its long dimension, then this pivots the central block 7 upward or downward around the central block shaft 8.
This pivoting motion is sensed by the two operating elements 15 and 16, which are likewise permanently mounted on the fastening case 5 the operating element 15 being located above the central block shaft 8 and the operating element 16 being located below the central block shaft 8 (see FIGS. 3 and 4). As illustrated in FIG. 3, there is a limit screw 17 with a compression spring 18 associated with each of these operating elements, which limits the pivoting motion of the central block 7 in one pivoting direction or the other and provides a central pivoting motion rest position of the central block 7 by means of the compression spring 18.
The aforementioned operating elements 15 and 16 in the illustrated example of embodiment in logical correlation control the adjusting unit of the automobile seat that causes the height adjustment of the seat upward or downward.
The single-handle 6 can also be pivoted around its handle housing shaft 11. In the illustration of FIG. 1, it is then no longer flush with the fastening case 5, but slopes downward or upward relative to it by an angle. The operating elements 19 or 20, which are fastened to the central block 7 but extend into the handle housing 6, are then actuated, so that they are actuated by the handle housing when the single-handle is pivoted.
In logical correlation, the operating elements 19 and 20 in the illustrated example of embodiment control the adjusting unit of an automobile seat that causes the tilting of the seat surface.
In the illustrated example of embodiment, two outer edges 21 and 22 of the central block 7 extend into the handle housing of the single handle 6, so that the latter cannot be excessively rotated when the seat surface is tilted, i.e., when the single handle 6 is pivoted around its handle housing shaft 11. A leaf spring or the like (not shown) can be provided to center the single handle 6 on its handle housing shaft 11.
In the operating mechanism described above, each of the operating elements 13, 14, 15, 16, 19, 20 is designed as an electrical operating switch for electrically actuated adjusting units of the automobile seat, but pneumatic operating valves can also be provided in the same way for pneumatically operated seat adjusting units.
1. An actuating device for controlling the operation of a vehicle seat, said seat having first, second, third, fourth, fifth, and si
