• TITLE Mounting bracket for a motor vehicle seat usable for different versions of a range of vehicles
• the subject of the invention is a support for fixing a motor vehicle seat which can be used for different versions of a range of vehicles.
• a motor vehicle may be fitted with different seats, in particular in row 2, which may have different methods of attachment to the base. Some seats are in fact fixed by screwing, others by interlocking (or pocketing), sometimes with indexing. It is then necessary to provide specific fixing brackets for each method of fixing a seat.
• a first object of the invention relates to a mounting bracket for a motor vehicle seat comprising
• a fixing part intended to be secured to a structural element of a motor vehicle, in particular a base or part of a base,
• a support part comprising two inclined walls with an L-shaped cross section, a first wall having a first through hole having a first shape, the second wall having a second through hole having a second shape and optionally a third through hole having a third form.
• the fixing support can receive various fixing / indexing elements through its orifices. It is thus understood that a single fixing support makes it possible to receive in fixing the seats having different fixing elements.
• the third optional orifice could advantageously be placed on the largest wall among the first and second walls.
• first, second and optionally third shapes of the first, second and third orifices respectively can thus be adapted to a specific fixing / indexing element.
• the support according to the invention can thus have separately or in combination:
• the support part may have a third wall and a fourth wall each connected to one side of the first and second walls so as to form therewith four faces defining a volume, optionally of parallelepiped shape. This makes it possible to structurally strengthen the fixing bracket of the invention.
• the fixing part may have a plurality of fixing walls, one part of which extends parallel or substantially parallel to the first wall and another part extends parallel or substantially parallel to the second wall, these fixing walls being intended to be applied against the walls of the structural element of the motor vehicle.
• the fixing walls may be integral with the third and fourth walls of the support part, other fixing walls may extend in the extension of the first and second walls.
• the fixing support can be made in one piece. It may, for example, be a molded or preferably stamped metal part.
• the invention also relates to a motor vehicle base intended to receive seats on which are fixed at least two mounting brackets according to the invention, in particular two identical mounting brackets.
• These fixing brackets can be fixed to the base by welding (when the fixing bracket and the base are metallic), by screwing, riveting or by several of these means.
• the first wall may extend horizontally or substantially horizontally and the second wall may extend vertically or substantially vertically and perpendicular or substantially perpendicular to a longitudinal direction of the base, the first wall forming an upper wall of the mounting bracket.
• the first and second walls can extend opposite the walls of the base.
• the invention also relates to a motor vehicle having a base according to the invention.
• the invention relates to a range of at least two types of motor vehicles comprising a base according to the invention, each type of vehicle being equipped with a specific seat the seat of which is provided with at least two fixing elements, the fixing elements of a specific seat of a type of vehicle being different from the fixing elements of a seat specific to another type of vehicle, each attachment element of a seat of a type of vehicle cooperating with at least one orifice of the same attachment support.
• the same fixing support can be used to receive different fixing elements of two types of vehicle.
• a fastening element of a specific seat of a type of vehicle can have a fitting finger inserted vertically through the first orifice of the first wall of a fixing support arranged horizontally or substantially horizontally, this finger of socket being engaged with said first orifice to secure the seat,
• Another fastening element of a specific seat of another type of vehicle may have a tab resting against the first and second walls of a fixing support, this tab having an orifice aligned with the second orifice of the second wall disposed vertically or substantially vertically for the passage of a screw or the like and, optionally, an indexing tab inserted vertically through the first hole of the first wall of the fixing support disposed horizontally or substantially.

• the terms front, rear, upper, lower refer to the front and rear directions of the vehicle, when the mounting brackets, the base and the seats are mounted on the vehicle.
• the X, Y, Z axes correspond respectively to the longitudinal (front to back), transverse and vertical axis of the vehicle, the latter resting on the ground.
• the vertical direction thus corresponds to the direction of gravity.

• a support portion 14 formed of two inclined walls 141, 142 with an L-shaped cross section, a first wall 141 having a first through hole 151 having a first shape, the second wall 142 having a second through hole 152 having a second shape and a third through orifice 153 having a third shape.
• orifice shape is meant here both the shape and the dimensions of this orifice.
• orifices of different shape may differ in their dimensions and in their shapes.
• the first, second and third shapes of the first, second and third orifices 151 -153 respectively, are here different in order to receive different fixing / indexing elements.
• the first orifice 151 and the third orifice 153 have a parallelepipedal shape.
• the first hole 151 is here rectangular, similar to a slot, while the third hole 153 is square shape.

• the invention is not limited to a particular shape of an orifice, which can be chosen according to the shape and dimensions of the fixing / indexing element that it is intended to receive.
• the support part 14 has a third wall 143 and a fourth wall 144, each connected to one side of the first and second walls 141, 142 so as to form therewith four faces defining a volume, here parallelepipedal in shape, open on two of its faces.
• the fixing part 12 has for its part a plurality of fixing walls 121, 122, 123, 124, 125 of which a part (the walls 123, 124) extends parallel or substantially parallel to the first wall 141 and another part (the walls 121, 122, 125) extend parallel or substantially parallel to the second wall 142.
• these fixing walls are applied against walls 31, 32, 33 of the structural element (the glazing bead 3) of the motor vehicle.
• These glazing bead walls 31-33 are connected in pairs and substantially perpendicular to each other, so as to form a rim 32 on which the fixing support 10 can rest vertically.
• the fixing support 10 shown here is secured to the base as follows:
• first wall 141 extends horizontally or substantially horizontally
• second wall 142 extends vertically or substantially vertically and perpendicular or substantially perpendicular to a longitudinal direction of the base (corresponding to the longitudinal direction of the vehicle)
• the first wall 141 forms an upper wall of the fixing support
• the fixing support 10 rests vertically on a rim of the structural element 3, here on the horizontal wall 32 thereof, and:
• the fixing walls 123 and 124 are supported and secured to the horizontal wall 32 and, -
• the fixing wall 125 which here extends substantially in the extension of the second wall 142 of the fixing support, is supported and secured to the vertical wall 33.
• the structural element 3 closes the volume defined by the walls 141-144 of the fixing support improving the strength thereof.
• the fixing element 10 can be secured to the glazing bead 3 by welding, screwing or riveting.
• a single fixing support 10 can thus be used for fixing different seats, as described below with reference to Figures 3 to 6.
