Abstract
The device enables a trim adjustment of the vehicle seat. An upper side of each upper section of a slide member carries two square members having vertical wings. The vertical wings maintain, at their upper ends either frontwardly or rearwardly of the seat, spindles on which is articulated a shoe-square. One of the two square members carries an articulation iron fitting enabling, by means of a reduction lever rotating with the mobile flange of each articulation, to raise a rear or front shoe-square in order that a seat frame fixed on the shoe-squares is displaceable by a clearance angle delimited according to needs either for a rear part of the seat or for a front part of the seat between a lower dead point and an upper dead point.
Claims8
A device enabling a trim adjustment of a vehicle seat, comprising
- a slide member having an upper section for each of two respective sides of said seat, for moving said seat forward and backward,
- two square members fixed at opposite upper end portions of each said upper section, each said square member having a vertical wing,
- a respective shoe-square operatively connected to said vehicle seat and a respective spindle for supporting each said shoe-square, each said shoe-square and spindle being associated with a respective one of said vertical wings,
- wherein at least one of the two square members on each said upper section of each said slide member carries an articulation fitting for providing rotation about a respective colinear axis of each pair of the articulation fittings at the same ends of said upper sections, each said articulation fitting including a fixed flange supported on the respective vertical wing and a mobile flange connected with a reduction lever, each said mobile flange and the respective reduction lever rotating about the axis of the respective articulation fitting for enabling, by means of each respective reduction lever rotating with the respective mobile flange of each articulation fitting about the axis of the respective articulation fitting, a raising of the respective shoe-square, in order that a frame of said seat fixed on the shoe-squares is selectively displaceable, at least for a rear part of the seat or for a front part of the seat, between respective lower and upper dead points PMB and PMH, each said reduction lever being connected at an end thereof by the respective spindle to the respective shoe-square.
