Definitions
- the present invention relates to a vehicle seat frame and a seat comprising such a frame.
- This seat has a rigid and common rigid frame for the backrest and the seat, which implies that the backrest has no means of adjustment relative to the seat.
- the metal frame is covered by a plastic shell, engaged on the top of the frame, so that a support towards the rear of the hull can cause a forward displacement of the upper part of the hull by rotation and it is likely to move by rotation of the upper part.
- the rotation is made possible by the nature of the material employed having a certain flexibility.
- the purpose of this seat is, in case of collision of the vehicle followed by a projection of the passenger against the back support part, the headrest part e is brought forward to minimize the risk of cervical injuries for the passenger.
- the design of this seat does not and is not intended to provide a seat with significant relief while ensuring an ongoing mechanical strength, especially in case of side impact, and mitigate the effects of undermarage.
- the object of the present invention is to provide a lightened seat base having robustness and integrity mechanical resistance effectively resistant to shocks and more particularly to lateral shocks as well as a suitable design capable of counteracting the effects of sub marring.
- the subject of the present invention is a seat armature of a vehicle seat comprising a metal profiled support, a plastic covering element and a metal seat structure, the plastic covering element being sandwiched. between the metal profile support and the metal seat structure to ensure the cohesion of the profiled support and the seat structure.
- the profiled support consists of two parallel struts having a Z-shaped end with inverted branches connected by a cross member.
- the cross member is secured to the bars at the inclined faces of the profiled support.
- the plastic element (4) covering has an identical profile at the edge of the profiled support on which it comes to fit over at least a large part of its length.
- the plastic covering element comprises in its front projecting zone a hemispherical half-shell.
- the metal structure is tubular.
- the structure (3) metal has a generally U-shaped with curved ends arcuate downwards.
- the metal structure comprises integrally connecting pieces.
- the metal profiled support, the plastic covering element and the metal structure are fixed integrally in the four corners of one assembly.
- the metal profiled support, the plastic covering element and the metal structure are fixed together at the front of the seat by screwing into the holes of the support, passing through the plastic element and engaged in the threaded ends of the structure, at the rear of the seat by screwing into the holes of the shafts of the support, passing through the plastic element and engaged in the threaded connection parts of the structure.
- the invention also relates to a motor vehicle comprising a seat frame of a vehicle seat comprising a metal profiled support, a plastic element of covering and a metal structure, having the above characteristics.
- FIG. 1 is an exploded perspective view of the seat of a seat comprising the components of the base and a view of its lining according to the invention.
- FIG. 2 is a perspective view of the assembled elements constituting the base of the seat devoid of its lining according to the invention.
- Figure 1 is an exploded perspective view of the seat of a seat comprising the constituent elements of the frame 1 and a view of its lining 10 according to the invention.
- the base forming the armature 1 consists of three elements is a support 2 of metal profile 2, a metal tubular structure 3 and a plastic cover piece 4 shaped to be sandwiched between the support 2 metal section and the structure 3 metal base to ensure the cohesion of the profiled support.
- the support 2 profiled consists of stretches 5, 6 parallel base, profiled whose end is raised by an inclined pan 5a, 6a extending by a portion of parallel shafts 5b, 6b to the base stretchers 5d, 6d having two bores 5C, 5c that is to say that the end ends with a Z-shaped inverted branches 7,8.
- Stretches 5b, 6b parallel are interconnected by a cross member 9 secured at the inclined faces 5a, 6a. Stretches 5b, 6b parallel are intended to be fixed on the slideways to move the seat.
- the plastic covering piece 4 is shaped to the elements it covers or receive.
- the edge 24 of its profile 11 is identical to the profile of the stretchers 5, 6 which it must over a large part of its length.
- the front zone of the plastic cover piece 4 has a projecting hemispherical half-shell 12. This shell is intended to enhance the lining at the front of the seat to counter the effects of submarining.
- various recesses 13 are provided for the passage of fasteners.
- the metal tubular structure 3 consists of two tubes 15,16 between them extending forwardly by curved ends in an arc 15a, 16a substantially less than 90 degrees.
- the end of the curved tubes comprises threads intended to come into correspondence with the bores 5c, 6c of the support 2.
- the tubes 15, 16 are slightly inclined 15b, 16b to end with a portion 15c, 16c parallel base stretchers 5d, 6d of the support 2.
- the two tubes 15, 16 are connected by a transverse tube 17 of identical section curved at 90 degrees.
- the structure 3 has a generally U-shaped shape 18, bent at the ends of the branches of the U.
- the structure 3 is optimally sized so as to ensure the attachment of the parts to withstand significant forces such as belt anchor 20, the attachment of the backrest and its movement by clevises 21, the fastening parts 22 of the means of deflection of the seat back and near the transverse tube connection 17 on the tubes 15d, 16d of the connecting pieces 23 at the rear end of the stretchers 5, 6 of the support 2 in metal profile 2.
- the view 10 shows the seat lining which comes using the assembly of the three elements of the frame 1 is a support 2 of metal profile 2, a metal tubular structure 3 and a part plastic cover 4 which ensures a comfortable seating of the user.
- the underside of the lining 10 is shaped to fit intimately on the frame 1 and comprises not shown fastening means. For a better comfort, the the top of the seat also has lateral reinforcements 10a.
- FIG. 2 is a perspective view of the three assembled elements constituting the armature 1 of the seat devoid of its lining according to the invention.
- the armature 1 consists of a support 2 made of metal profile 2, a metallic tubular structure 3 and a plastic cover piece 4.
- the three elements 2, 3, 4 are assembled integrally with the aid of FIG. screw fixed in the lower corners 25 and upper 26 of the cover piece.
- the plastic covering piece 4 has flanges 26 on its edge 25 which masks the largest length of the stretchers 5, 6 in order to obtain a good perceived quality.
- the tubular structure 3 is the part that supports the belt anchor 20, the fastening of the backrest and its movement by clevises 21, the fastening parts 22 of the three elements 2, 3, 4 constituting the reinforcement 1 together.
- the plastic covering piece 4 ensures the cohesion and solidarity of the elements 2, 3 made of steel. This cover piece 4 undergoes very few physical constraints, its role is to ensure an anchor point of all the mechanical elements. In this way, the armature 1 thus formed has excellent mechanical strength while reducing considerably mass compared to a conventional seat seat.
