A seat unit can be screwed automatically to the body platform at four fixing points without the need to alter the seat setting during screwing and has a sufficiently rigid connection, in particular a sufficiently firm connection for seat belts which are fixed to the seat, to the body platform. The fixing regions are provided in the floor rail itself, in particular in each case at a distance from the free ends of the latter and in a profile region, extending essentially parallel to the body platform, of the floor rail. These regions are joined directly to a steep wall and, with the latter, in each case form a ramp, and are oriented such that they enclose as small an angle as possible with the floor rail, although this angle is kept sufficiently large that, in an installation setting of the seat unit, the axes of the holes extend in front of the front side of the seat and behind the rear side of the seat with a clearance of a few centimeters, which makes possible the use of a screwdriver unit.

Screw-retained motor-vehicle seat unit

A seat for use in a motor vehicle has a body supporting unit and a back rest which is pivotably connected to the body supporting unit by two hinges having pintles provided with eccentrics which cause the back rest to perform a composite pivotal and transverse movement while it changes its orientation with reference to the body supporting unit. The back rest carries two pivotably mounted arm rests which are connected to the back rest and to the body supporting unit by linkages serving to ensure that the orientation of the arm rests remains substantially or completely unchanged while the back rest is pivoted with reference to the body supporting unit. A second linkage can be used to pivot the front ends of the arm rests rearwardly and upwardly when the back rest is lifted with reference to the body supporting unit and is pivoted forwardly toward the dashboard in a two-door motor vehicle in order to afford convenient access to the rear seats or to permit a passenger to leave a rear seat with a minimum of effort.

Seat with adjustable back and arm rests

In an articulated fitting for vehicle seats, particularly motor vehicle seats, having an upper fitting element (4) to be connected with the back rest, a lower fitting element (3) to be connected with the seat portion, an intermediate element (5), which is pivotably connected both with the upper fitting element and with the lower fitting element about a hinged axis (6) and a lower-lying folding axis (13), respectively, and having an adjusting and holding device that engages the upper fitting element (4) and the intermediate element (5) for the adjustment of the angle of inclination of the back rest and the folding lock (14,17,18,20) which permits a pivoting of the upper fitting element (4) and the intermediate element (5) about the folding axis (13) only when in the opened condition, the connecting line between the pivot axis (6) and the folding axis (13) when the folding lock is closed, encompasses an angle of at most 30.degree. with a line extending vertically downward from the pivot axis (5) in the assembled position.

Articulated fitting for vehicle seats

A hinge assembly for supporting the back part of a motor-vehicle seat on the fixed seat part comprises two hinges. Each of these hinges comprises a first hinge element pivotal on the seat part about a first axis between a rest position and a pivoted position and a second hinge element on the back part and pivotal on the respective first hinge element about a second axis through a plurality of angularly offset adjustment positions. Each second hinge element is provided with a plurality of teeth and each first hinge element has a pivotal pawl with teeth engageable with the teeth of the respective second element so as to hold the second element when these teeth are engaged in any of a plurality of angularly off-set adjustment positions. Mechanism is provided connected to both of these pawls for displacing the teeth thereof into and out of engagement with the respective teeth of the second formation. In addition a cam is provided which serves to lock out the adjustment means when the back part of the seat and the corresponding second hinge elements have been pivoted from the rest position, so that when the seat back has been pivoted forwardly the adjustment mechanism cannot be operated to maladjust the seat.
