Abstract

The seat frame can either come with a height adjustment device of the seat frontal edge or not. Its seat carrier has at least one side part, one front arm means and one longitudinal adjustment device. The side part is provided with a first bore and a second bore. The front arm means is either realized by a parallelogram arm or a pair of arm means. The parallelogram arm has a first bearing member cooperating with the first bore. The pair of arm means is composed of an upper arm and a lower arm and a device for adjusting the angular position of the upper arm relative to the seat carrier. The upper arm is provided with a second bearing member which is spaced from the common joint and cooperates with the second bore. Both arms are pivotally joined together in a common joint. The lower arm shows a distance between the common joint and the bearing means, which is substantially of the same length as the distance realized by the parallelogram arm and measured between the first bearing member and the lower pivot joint.
