Facilitating boarding a to the rear seats one two-door Kraftfahi ^ sisgeSj, around the axis of the front lower joints are pivoted, with one through the Weight of the seat, a certain torque must be overcome ο

The invention is based on the object of a seat of to create the type in question, which in terms of its position in the longitudinal direction relative to the pedals and the steering ' wheel can be easily adjusted to the size of the seated person istg in the operation of which the above-mentioned torque is essentially eliminated and by means of it Nevertheless, the entry width for the rear seats has been increased be kamu

According to the invention, this object is achieved in that the locking device is designed in such a way that the seat can be adjusted forwards beyond the angular range required to adapt it to the leg length of the seated person ₀

Thus, the seat frame can with four rods angelehkt at the bottom eein, parallel to the seat frame and the bottom two Qelenkvierecke form ₀ The rear supports can also fixedly connected to the Slterahmeη and disposed at the bottom so that • it Cwar at the bottom in the longitudinal direction of the Sitsea slide * but cannot rise from the ground «The site
