First Claim
1. A seat frame of a motor vehicle seat comprising:
- a seat carrier including two side parts that are oriented transverse to a front axis and to a rear axis, a front part, and a rear part;
a back rest hinged to said side parts;
a pivotal bridge being pivotal about one of said front and rear axes, said bridge comprising a tie bar and two side arms, said bridge further being one of i) pivotal about said front axis and comprising said front part and ii) pivotal about said rear axis and comprising said rear part;
a transverse tube being arranged centrally with respect to the other one of said front and rear axes and is pivotal about said other axis;
at least one pivotal support having a projection, the transverse tube being solidly connected to the at least one pivotal support; and
an adjustment device includinga motor-driven drive unit having a first end and a second end, the first end being arranged for pivotal movement about a hinge shaft that is substantially centered on that axis of the front and rear axes about which said pivotal bridge is pivotal, and the second end being arranged for pivotal movement around the projection, andat least one inner arm that connects said tie bar to said hinge shaft and is located in proximity to said drive unit,wherein the hinge shaft is shorter than the distance between the two side parts and at least one of (i) the hinge shaft does not contact the two side parts and (ii) the hinge shaft contacts one of the side parts, and wherein during actuation of said motor-driven drive unit said transverse tube is pivoted about said other axis.

Abstract
The invention relates to a seat frame of a motor vehicle seat with a seat carrier having two side parts that are oriented transverse to a front axis and to a rear axis, a pivotal bridge being pivotal about at least one of said axes, said bridge comprising a tie bar and two side arms, and with an adjustment device having a motor-driven drive unit. The drive unit is arranged for pivotal movement about a hinge shaft that is substantially centered on that axis of the two axes about which said pivotal bridge is pivotal. Said hinge shaft is shorter than the distance between the two seat parts and is not in contact with said two seat parts, but if at all with only one side part. There is provided at least one inner arm that connects said tie bar to said hinge shaft and is located in proximity to said drive unit.
