Abstract
A frame for a vehicle seat comprises two side parts and swing arms pivotable in relation thereto for height adjustment of the frame. The swiveling of the swing arms can be caused by operating two actuator arms. Each actuator arm is associated with another swing arm so that the associated swing arm can be swiveled by actuating the respective actuator arm.
Claims18
A frame for a vehicle seat comprising
- two side parts and swing arms pivoting in relation to the side parts, said frame being height adjustable by means of swiveling the swing arms, whereby said swiveling of the swing arms can be caused by operating at least two actuator arms,
- each actuator arm being associated with a respective swing arm of the frame so that the respective swing arm can be swiveled by actuation of a respective actuator arm, said at least two actuator arms being twistable mounted at an anchor point to the respective swing arm so that, upon actuation of said at least two actuator arms along a direction of actuation, the swing arms can be swiveled about a pivot point and the side parts of the frame can be moved in a height adjustment direction,
- the actuation of said at least two actuator arms along the direction of actuation being synchronized via a synchronization bar so that the swing arms swivel in synchronized fashion, said synchronization bar extending between said side parts and being twistable mounted at connection points on the side parts,
- wherein said connection points are located at most one third of a side part length of each respective side part away from a front end point of the respective side part in a front end region of the respective side part, and
- wherein said swing arms includes front swing arms that are twistable arranged in the front end region of the respective side part, said front swing arms arranged on different side parts and not being connected to each other via a transverse pipe.

A frame for a vehicle seat comprising
- two side parts, two swing arms mounted for pivotable movement relative to the side parts, said frame being height adjustable in response to pivotable movement of the swing arms, and at least two actuator arms,
- each actuator arm being associated with a respective swing arm of the frame so that the respective swing arm can be pivoted by actuation of each respective actuator arm, said at least two actuator arms being twistable mounted at an anchor point to the respective swing arm so that, upon actuation of said at least two actuator arms along a direction of actuation, the swing arms can be swiveled about a pivot point and the side parts of the frame can be moved in a height adjustment direction,
- the actuation of said at least two actuator arms along the direction of actuation being synchronized via a synchronization bar so that the swing arms swivel in synchronized fashion, said synchronization bar extending between said side parts and being twistable mounted at connection points on the respective side parts,
- wherein said connection points are located at most one third of a side part length of the respective side part away from a front end point of the respective side part in a front end region of the respective side part, and
- wherein actuator pinions are rigidly affixed to ends of the synchronization bar, said actuator arms each comprising gears, each actuator pinion meshing with the gears of a respective actuator arm so that any rotation of the actuator pinion and, therewith, an actuation of the actuator arms happens in synchronized fashion.
