Embodiment Construction

[0013] 1 and 2 show in detail a backrest frame 1 which is the supporting structure of the backrest of a motor vehicle seat. With the aid of the side reclining fittings 2, the backrest frame 1 and thus the entire backrest on the seat part of the vehicle seat can be adjusted in its functional position in terms of inclination in order to increase seat comfort, and on the other hand can also be tilted forward of. In both cases, the pivoting of the backrest takes place about the same axis, provided that the reclining fitting 2 is also formed for the coaxial tilting of the backrest. The connection of the backrest to the seat part of the vehicle seat takes place via the fitting part 3 fastened to the seat.

[0014] The reclining fitting 2 also has a pivotable fitting part 4 relative to the seat-fastened fitting part 3 , which is non-positively connected to the backrest frame 1 and can be connected to a so-called fitting center of the reclining fitting 2 , which is connected to the d...

Abstract

The invention relates to a swing angle restricting device of an accessory part used for backrest inclination adjustment on a car seat. The device is arranged on the inclination adjustment accessory. The drive motor of the braked drive is positively connected to a reduction drive. The pivot angle is mechanically limited by end stops, and in order for the backrest to be able to be tilted forward, the fitting part which pivots together can be disengaged from the backrest. In order to prevent the fitting part from hitting the mechanical end stop when the backrest is tilted, a rotary sensor for measuring the angular position of the fitting part connected to the backrest is arranged on the shaft connecting the drive motor to the reduction gear. Determine the two end angular positions of the fitting part, beyond which the drive motor is switched off, and in which there is sufficient angular margin available when the backrest is swiveled without the fitting part touching on the end stop.

Description

technical field [0001] The invention relates to a swing angle limiting device of an accessory part used for adjusting the inclination angle of a backrest on a car seat. Background technique [0002] For the inclination adjustment of the backrest in car seats, accessories are increasingly being used which are equipped with devices which on the one hand enable a so-called comfort adjustment of the backrest by means of an electric motor and on the other hand the backrest relative to the car seat The seat of the chair is reversible in order to facilitate access to the rear seat, for example in two-door vehicles. Not only when adjusting the comfort, but also when tilting forward and backward, the backrest pivots about the same axis, which relates to the axis of rotation of the shaft. The shaft connects the inclination fittings on both sides to each other and to the drive motor. In these cases it is referred to as an inclination fitting with coaxial tilting stages. [0003] Whe...
