Definitions

• the present invention relates to a fastening system for a seat including a motor vehicle, on a floor of a vehicle including a motor vehicle.
• the stowage of a seat in a vehicle is by two rails that are reported on the vehicle floor. These slides are generally oriented longitudinally with respect to the direction of movement of the vehicle.
• the seat has, for its part, slides that allow it to engage in the slides and move relative to them.
• the seat is further equipped at its base with locking means that can lock the seat in several positions according to the needs of a user.
• the seats of rank 1 that is to say the seats in front of the front doors of the vehicle are, with rare exceptions, mounted on slides and are therefore longitudinally adjustable.
• the seats of rank 2 and tier 3 can also be mounted on slides. Therefore, since this type of vehicle can have up to 7 to 8 seats, there are 7 to 8 sets of two parallel rails that are fixed in the floor.
• the dimensional dispersions that can be seen in the fixing zones of the slides can generate parallelism defects of the slides in the directions related to the vehicle, longitudinal X and transverse Y defining the plane of the vehicle floor but also in the vertical direction Z.
• Document FR-A-2 835 790 shows a way of managing the parallelism defects of the slideways which provides for the insertion of wedging members into the slides.
• the wedging members shown in this document make it possible to absorb the dimensional dispersions in a very efficient manner, but at the expense of a certain mechanical complexity.
• the invention therefore relates to a seat receiving profile comprising two parallel sliding members; the profile incorporates two lateral parallel rails each having two wings forming a U likely to respectively accommodate the sliding members of the seat, and in that at least one side face of a profile has a groove dovetail susceptible to receive sliding members of a seat.
• the invention proposes to ensure the reception of a seat by a single profile that integrates two slides.
• This profile which can, for example, be made by extrusion has the characteristic of incorporating the two rails in which the sliding members of the seat.
• the management of the parallelism of the slides which is critical for the proper functioning of the seats is treated at the level of a single component in this case a profile.
• the central part of the profile comprises a box positioned between the two slides. This provision is intended to increase the inertia of the profile. It may be recalled that, in the event of a sharp deceleration following an accident of the vehicle, part of the energy must be cashed by the connection between the seat and its support.
• the box comprises five longitudinal cells delimited laterally by the walls of the slides and centrally by four webs of material.
• At least one of the slides is provided in at least one of its wings with a plurality of holes distributed at a regular pitch. These holes can accommodate locking members such as, for example, pins that allow to lock the seat in any position of the user's choice.
• the invention also relates to a vehicle having a floor equipped with two profiles as previously described, each of which can receive a seat.
• the profiles are oriented relative to each other, so that the dovetail grooves face each other.
• the two sections arranged side by side can each receive a seat which is worn half by each of them.
• a seat storage cup is formed in the floor of a vehicle between the two sections.
• This arrangement is very advantageous insofar as the central seat that can be retracted into the bowl is retained by two grooves that do not interfere with this bowl.
• At least one of the seats has a seat supported by a base, the seat can move transversely to the base.
• This provision is extremely useful in the case of a vehicle equipped with two profiles embedded in a bowl in which stows a central seat. When this seat is stored, the two seats supported by the profiles can be move transversely towards each other to occupy the space left by the central seat.
• the seat may comprise a lower base comprising two parallel slides that can be engaged in the two rails of a profile and an upper base supporting the base connected to the lower base by at least one rail oriented perpendicular to the sliders on which the upper leg can slide relative to the lower leg.
• Figure 1 is a cross-sectional view of a vehicle equipped with two seat attachment profiles
• Figure 2 is a top view of this vehicle
• Figure 3 is a perspective view of a profile
• Figure 4 shows in perspective a seat fixed on a profile
• Figure 5 shows a possible configuration of a vehicle.
• a vehicle whether it is a motor vehicle, rail or air, has a floor 2 on which are fixed one or more seats 3 allowing passengers to sit and travel in this vehicle.
• the floor of the vehicle which, in this case is a motor vehicle, is provided with two profiles 4 which are fixed, for example, by bolting on the floor 2.
• Each of these sections 4 incorporates two side rails 5 which, in the example shown, are separated by a central box 6.
• Each of the slides 5 has a cross section with two wings 8 in the general shape of U.
• the end of each of wings 8 is provided with a lip 9 facing the inside of the slide.
• the profiles 4 can be extruded aluminum. Other metals can of course be considered to make these profiles and it can also be quite conceivable to make them composite material. It is also noted that in each of the wings 8 of the slides 5, bores 10 are provided at a regular pitch. We can also observe the presence of a box 6 between the two slides 5, this box 6, in the example shown has five cells; it consists of three central cells which are separated by four webs of material 1 1 and two lateral cells which are connected to each of the slides 5.
• Figure 2 shows how the profiles can be arranged with respect to the general architecture of the vehicle floor.
• the fixing of the tier 2 and tier 3 seats of the vehicle is provided by two parallel rails 5 which are oriented in the longitudinal axis of the vehicle.
• the two sections 4 frame a substantially parallelepipedal bowl 12 in which can be arranged a retractable seat 3.
• the two rails 5 are provided with a groove 14 dovetail which can serve as. guiding means to a central seat 3.
• the dovetail shape is illustrative of the general function to ensure the reception and guidance of a sliding member of a central seat.
• the seats 3 which will come to be fixed on each of the two sections 4, they may be of a conventional structure.
• These seats may comprise a base which has fasteners on one of the profiles 4.
• the base in general, incorporates two slides 16 whose section is complementary to that of the two rails 5 present in the section 4; these two slides 5 are by parallel construction, whatever the flatness or size defects of the floor on which the profile 4 rests.
• Another advantage of the invention is that, not only can the profiles ensure the reception of one or two seats placed in tandem, but two sections 4 arranged parallel to each other can ensure the attachment of a seat central which, in the example shown, can be retracted into the bowl in the center of the vehicle.
• central seat is meant a seat that comes to take a position between each of the profiles.
• Figure 5 illustrates this case with a central seat 3 retracted in the bowl.
• each of the slides 16 is equipped with means for locking longitudinally the seat relative to the profile. These means may, for example, take the form of a stud coming into one of the holes provided in the wings of the slides.
• the upper leg 1 8 which receives the seat and the hinge mechanism of a backrest, it is connected to the lower leg by two transverse rails 20 which allow a movement in a direction transverse to the vehicle of the seat and the seat back.
• the provision for bringing two seats transversely can be put to use in a vehicle having a configuration of 2 - 3 - 2 that is to say two seats of rank 1, three seats of rank 2 and two seats of rank 3 in which the fixing of the seats of rank 2 and rank 3 is made exclusively by two sections which extend over the entire length of the rear part of the vehicle.
• rank 2 three seats, two side seats supported by each of the profiles and a central seat supported by each of the profiles at the grooves dovetail; with regard to the rank 3, it may be provided to have seats of the aforementioned type, that is to say, allowing a transverse displacement which, taking into account the architectural requirements including wheel passage, must be brought transversely one of the other.
• a vehicle could use four fully interchangeable seats that can be used as tier 2 side seats and tier 3 seats, while providing for the attachment of these seats only two profiles that extend on the floor of the vehicle at row level 2 and ranks 3.
• the invention proposes in the first place a profile for ensuring the reception and fixing of a seat in which the parallelism is totally independent of the flatness and possible dimensional dispersions of the floor on which the profile is fixed and secondly the invention allows a simple way to ensure the attachment of a central seat retractable or non-retractable.
• the invention is not limited to the embodiments described above by way of non-limiting examples, but it encompasses all the embodiments.
