ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a seat for an automobile vehicle including a seat cushion which supports a seat back and which is intended to be fixed on the vehicle floor by means of feet, the seat cushion comprising a seat cushion structure which includes at least two lateral flanges intended to support the seat back and at least two tubes transversely connecting the two lateral flanges, at least two feet being added on each of the tubes.
The present invention relates in particular to seats intended to be installed aboard vehicles of the “monospace” type.
BACKGROUND OF THE INVENTION
The front and rear fixing feet of the seats currently encountered are fixed directly on the two lateral flanges of the seat cushion.
These seats are intended to be positioned on the floors of the vehicles thanks to seat feet reception means. These reception means are spaced from each other by a gap which differs from one vehicle model to another. The seat cushion flanges must therefore be adapted to each type of vehicle in order that the feet which they support have a corresponding interval between them, which necessitates specific tooling for each type of seat cushion flange.
Consequently, it is not possible to use the same manufacturing tools to make the lateral flanges of seats intended to be mounted in several types of vehicles, the spacings of the fixing means of which are different, from which a relatively high manufacturing cost results.
The present invention has the object of supplying a seat for an automobile vehicle the structure of which does not necessitate using different manufacturing tools as a function of the interval between the fixing feet to be obtained.
SUMMARY OF THE INVENTION
For this purpose, according to the invention, an automobile vehicle seat of the aforementioned type, is essentially characterized in that each foot is spaced from the corresponding flange by a strut.
Consequently, the interval between the seat feet is easily modified by installing the seat feet over the length of the transverse tubes.
The seat according to the invention may possibly comprise in addition one or more of the following characteristics:
the vehicle floor comprises reception means for the feet which are spaced by a pre-specified value, the length of each strut being adapted to obtain an interval, between two feet carried by the same tube, of length approximately equal to aforesaid pre-specified value;
the two flanges each include a front part and a rear part, the two front parts and the two rear parts being respectively connected by the transverse tubes;
the tubes and the feet are made of metallic parts, the feet being fixed on the tubes by welding;
the struts are mounted to rotate in the two lateral flanges;
the transverse tubes each include two free ends which are crimped in the struts, so that the transverse tubes are fixed in aforesaid struts;
the seat is removable; and
the tubes are rectilinear at least near the lateral flanges.
The present invention has the additional object of a seat manufacturing process defined above, this process comprising stages consisting in:
slipping two feet onto each of the two tubes
adjusting the struts of the feet on each tube and welding the feet onto these tubes;
mounting the struts on the tubes and abutting the struts against the feet;
positioning the struts in the flanges; and
crimping open the ends of the tubes over the struts.
