First Claim
1. A vehicle seat comprising a scissors stand for adjusting a seat height, the scissors stand comprising:
- intersected rockers;
at least one frame; and
a bearing device movably guiding the rockers relative to the frame, the bearing device comprising;
an insert defining or being connected to a first guide and a second guide, the insert having a foot region, a head region extending parallel to the foot region and a side region extending at a right angle to the foot region;
a bearing roller rotatable about a bearing axis and interacting with the first guide; and
a compensating roller rotatable about the bearing axis and interacting with the second guide, the second guide being defined by or being attached to the foot region of the insert, at least one of the side region of the insert and the head region of the insert being fastened to the frame, and the foot region is of an elastic design and presses against the compensating roller, the frame having a C-shaped profile which is open toward an interior of the vehicle seat and comprises an upper limb, a lower limb running parallel to the upper limb and a base limb which runs at a right angle to the upper limb and connects the upper limb to the lower limb, at least one of the side region of the insert is fastened to the base limb and the head region of the insert is fastened to the upper limb, the foot region of the insert being arranged at least substantially parallel to the lower limb, wherein a gap is provided between the foot region of the insert and the lower limb.

Abstract
A vehicle seat (1), in particular a commercial vehicle seat, includes a scissor-type (scissors) framework (3) for adjusting the height. The scissors framework has intersecting rockers (8a, 8b) and at least one frame (5, 7), and at least one bearing device (21) for movably guiding the rockers (8a, 8b) in the frame (5, 7). A rotatable bearing roller (14) interacts with a first guide and a rotatable compensation roller (36) interacts with a second guide attached to a base region (52) of an insert (60). A lateral region (54) of the insert (60) extends perpendicularly to the base region (52) and is fixed to the frame (5, 7) and/or a head region (50) of the insert (60), extending parallel to the base region (52), is fixed to the frame (5, 7). The base region (52) is resiliently designed and presses against the compensation roller (36).
