Brief Patent Description - Full Patent Description - Patent Application Claims
[0001] The present invention relates to a seat for a vehicle, and a motor vehicle equipped with this seat. [0002] The front seats of motor vehicles are generally provided with the possibility of adjusting the position of the seat relative to the structure of the vehicle and adjusting the angle of a backrest relative to a cushion. To achieve this, the backrest is connected to the cushion by a connection articulated along a transverse axis and the cushion is mounted on the floor of the vehicle by means of slide bars. An adjustable seat for a motor vehicle is known from the document FR 2 801 851. [0003] Such a seat, however, which has to be resistant in the case of violent impact of the motor vehicle with an obstacle, has a frame and hinges accordingly provided which are bulky and heavy. A bulky seat is obtained without, however, obtaining satisfactory rigidity of the seat. [0004] The object of the present invention is a front seat for a motor vehicle allowing the design of a lightweight and slim frame to provide a seat which is space efficient and retains a space in a passenger compartment, whilst improving the rigidity and the resistance of the seat. [0005] The object of the present invention is also a front seat for a motor vehicle allowing the protection of the occupants to be improved in the event of longitudinal or lateral impact sustained by a vehicle or in the event of the vehicle overturning. [0006] Such a front seat for a motor vehicle comprises a backrest frame, lower fixing means for rigidly fixing the backrest frame to a lower structural element of a passenger compartment, and upper fixing means for rigidly fixing an upper part of the backrest frame to an upper structural element of a passenger compartment. [0007] The upper and lower fixings of the backrest frame allow the backrest to be held in place relative to the vehicle structure and thus allow an increase in the rigidity of the seat as a whole. The seat may be provided with a slim and lightweight frame without impairing the rigidity of the seat or its resistance, in particular in the event of impact of the vehicle with an obstacle. [0008] Structural element is understood to be a pillar, a cross-member, a side member, a central beam or a sheet metal roof or floor forming the structure of the vehicle. [0009] Advantageously, the backrest frame and the lower and upper fixing means are suitable for forming means for rigidifying a passenger compartment structure of the vehicle. Thus, the backrest frame connecting a lower structural element to an upper structural element of the vehicle allows the vehicle structure to be reinforced. The rigidity of the vehicle is improved, in particular in torsion. The resistance of the passenger compartment in the event of impact is increased and the protection of the occupants is improved. [0010] In order to maintain an adjustment of the backrest, backrest upholstery may be provided mounted vertically mobile on the backrest frame. [0011] In one embodiment, the backrest frame is fixed directly to a lower structural element by lower fixing means. A cushion frame may be mounted vertically mobile relative to the backrest frame and/or mobile in rotation along a horizontal axis. [0012] In a further embodiment, a cushion frame is rigidly fixed to the backrest frame, and the lower fixing means rigidly connect the cushion frame to a lower structural element of a passenger compartment, the cushion frame, the backrest frame and the lower and upper fixing means being suitable for forming means for rigidifying a passenger compartment structure of the vehicle. The cushion and backrest frames may be formed integrally. [0013] Advantageously, the lower fixing means comprise a single leg supporting the cushion, said leg able to be rigidly fixed to a lower structural element of the passenger compartment. The single leg allows a space to be created for the feet of passengers located on a row of rear seats. [0014] In one embodiment, the upper fixing means comprise at least one upper arm extending from an upper part of the backrest frame and able to be rigidly fixed on the opposing side to an upper structural element of the passenger compartment. [0015] Advantageously, the seat is provided with at least three fixing points for a seat belt. The rigidity conferred to the seat by the upper and lower fixings allows the backrest to resist the tractive force exerted by the seat belt on the upper part of the backrest when the passenger is projected forward. [0016] The invention also relates to a motor vehicle comprising at least one seat according to an aspect of the invention. [0017] The backrest frame of the seat may be rigidly fixed to lower cross-members, to a lower central beam, to a lower side member, and/or to a lower portion of a pillar of the vehicle structure. Similarly, the upper part of the backrest frame may be rigidly fixed to an upper cross-member, to an upper central beam, to an upper side member and/or to an upper portion of a pillar of the vehicle. [0018] With the backrest frame being fixed, and in particular when the seat is intended for the driver, a control unit may be provided which is mobile along a longitudinal axis relative to the seat in order to allow an adjustment of the driving position. [0019] The present invention and its advantages will be better understood by studying the detailed description of embodiments made by way of nonlimiting example and illustrated by the figures, in which: [0020] FIG. 1 shows a schematic view in longitudinal section of the passenger compartment of a motor vehicle provided with a seat according to an aspect of the invention; [0021] FIG. 2 shows a partial transverse sectional view along II-II of the passenger compartment of a motor vehicle provided with a seat according to FIG. 1; and [0022] FIG. 3 shows a schematic lateral view of a seat according to an aspect of the invention. [0023] In FIG. 1, a passenger compartment 1 of a motor vehicle, shown partially, is defined by a floor 2, an instrument panel 3 provided with a steering wheel 4, a front windshield 5 and a roof 6. A front driver seat, denoted by 7 in its entirety, is arranged opposite the steering wheel 4 and located in front of a row of rear seats (not shown). [0024] The seat 7 comprises a cushion 8 and a backrest 9. A frame of the seat 7 is shown in solid lines, padding or upholstery of the seat 7 being defined by dotted lines.
