According to the present invention, the problem is that the backrest has a backrest plate provided between the rocking beams, and the backrest plate extends from the rocking axis of the rocking beam. At least spaced to correspond to the depth of the seat part, while the seat part is swingably pivoted on both sides to a support piece fixed in the lower range of the swing beam and on both sides Is connected to the vehicle floor via a connecting rod in the form of a rotary joint, and this support piece can be locked by the seat portion in the use position and the restraining lever that is loaded in the restraining direction. Will be solved. A passenger seat of this kind is suitable for storage as a whole and can be mounted on the vehicle floor as a whole.

In order to form a restraint device for the fixed connection between the backrest and the seat part in the position of use, a support piece fixed to the rocking beam of the backrest is an axial pin for swingably supporting the seat part. In addition to this, it is advantageous to have a restraint pin, which in the use position of the auxiliary seat is engaged by a one-sided open slit on a restraint lever pivotally mounted on the seat part. There is. In this case, the expense of components for supporting the auxiliary seat in the use position can be reduced by the fact that the connecting rod and the restraining lever are supported on the same axle pin fixed to the seat part.

In order to be able to position the seat part at a sufficient height and to simplify the manufacture of the seat part, according to another feature of the invention, the frame of the seat part is provided with a seat of this seat part. A support plate is provided in each of the rear regions of the longitudinal sides, the support plate pivotally mounting a connecting rod and a shaft pin which forms the pivot axis of the seat part and which connects the seat part with the support piece of the backrest. It also supports a shaft pin that swingably supports the restraint lever. The load of the restraining lever acting in the restraining direction is advantageously generated by the tension spring acting on the force arm of the restraining lever, and the restraining lever moves to the release position in the direction opposite to the acting direction of the tension spring. Can be done.

The backrest when the auxiliary seat is in the unused position so that a flat loading surface can be formed in the unused position of the auxiliary seat and that the auxiliary seat in the unused position can be protected from damage. The rear surface of the seat forms a loading surface part which is complemented by a connecting part which is pivotally connected to the upper surface of the backrest, while the lower surface of the backrest plate is pivotally supported by The cover plate attached to the vehicle floor is connected at the back. This cover plate covers the seat portion in the unused position of the auxiliary seat.
