Embodiment Construction

[0068] Fig. 1 shows the plan view of the adjustment main body of the pawl type adjustment device according to the first embodiment of the present invention, which drives the displacement of the ratchet relative to the fixed base element through the rectangular drive element, the adjustment main body is located in the central position, that is, the starting position, the said The adjustment body does not move relative to the base element. The pawl-type adjustment device of the present invention includes an adjustment body 2 that can move on a fixed base element 1 , and the surface of the adjustment body has a first linear toothed portion 3 and a second linear toothed portion 4 arranged parallel to each other.

[0069] The base element 1 , the adjusting body 2 and the driving element 5 are all in the shape of a flat plate, that is, they all have a small thickness.

[0070] Said driving element 5 is arranged so as to be movable between first and second linear toothed parts 3, 4, ...

Abstract

The invention relates to a ratchet-type adjustment device for the ratchet movement of an adjustment body (2) relative to a fixed base element (1) by means of a rectangular drive element (5), wherein said drive element (5) can be moved along a linear toothed portion (4) To move, the linear toothed part (4) is mounted on the adjustment body (2) on either side of the drive element (5) and locked into the first linear toothed part (3), by means of the first ratchet The elements (8a, 8b) serve as drive toothed parts, and the adjusting device further comprises at least two second ratchet elements (14a, 14b) pivotally mounted on the fixed base element (1), wherein the ratchets The element can lock into the second linear toothed part (4) as a blocking or braking toothed part, blocking the movement of the adjusting body (2) relative to the fixed base element (1).

Description

technical field [0001] The invention relates to a ratchet-type adjustment device, which causes an adjustment body mounted on a base to generate a ratchet displacement through a rectangular driving element, and has linear serrated protrusions installed on both sides of the driving element of the adjustment body. [0002] Such linear pawl type adjustment devices are used to move the seating surface of the vehicle forward or rearward at will relative to the base. Such an adjustment device enables the adjustment main body to produce multi-stage ratchet wheel adjustment through the rectangular driving element, and can also be used to realize the height adjustment of the seat surface. Background technique [0003] German Patent No. DE 10039501 A1 discloses a pawl-type adjustment device with an adjustment body movable relative to a base element, such as the base of a seat surface, which is connected to the seat surface. The adjustment main body can move relative to the base elemen...
