To mount the equipment to the chassis, the equipment is moved in the direction of the base 12, for example, along a vertical axis (y). If the lower part of the body of the leg 15 is chamfered, the leg 15 can be easily inserted into the fixing opening 14. As the equipment is moved towards the base side, the surfaces 15a, 15b of the legs forming the contact surfaces come into contact with the guiding surfaces formed by the surfaces 13a, 13b, and the legs 15 Rotate around the axis (y) against the stressing of the restoring spring 22 until the upper part 17b comes into contact with the guiding surfaces 13a, 13b. At this time, since the second direction (z2) of the leg coincides with the fixing opening 14, the leg has rotated to the insertion position. Once the body of the leg has completely passed through the guide surfaces 13a, 13b of the fixing opening, the lower part 18b of the cylindrical shaft 18 is inserted into the corresponding cylindrical part of the fixing opening 14, and the leg is restored. The state is such that only the force applied by the spring 22 is received. This force returns the leg to the rest position, in which the lower part 17a is aligned with the longitudinal direction of the fixing opening 14 and the upper part 17b is at an angle θ with respect to the longitudinal direction of the fixing opening 14. Tilting and consequently the equipment is fixed to the floor as shown in FIG. 2b, which is a cross-sectional view along axis IIB-IIB which coincides with axis (z2) in FIG.

The recess 25 is provided in the lower surface 12a of the base 12 and can be easily received.

  The recess 25 may be, for example, prismatic in shape, such that the bottom surface is triangular and the bottom surface extends in a plane orthogonal to the cross-sectional view of FIG. 3B. In this case, this recess 25 is provided with a high recess beyond the cross-section of FIG. 3b to receive the higher raised second end 27 when the leg 15 is mounted in the base 12. This recess may extend in the direction of the cross section in FIG. 3b with a reduced degree of depression up to a low recess which receives the other end 26 of the upper surface 17b of the upper part 17b of the body of the leg 15.

  With such a configuration, play between the leg 15 and the base 12 can be eliminated.

(Third embodiment)
FIG. 4 shows a fixing leg 15 according to a third embodiment of the present invention. According to the third embodiment, the fixing leg 15 is composed of two parts combined. First, the skeleton 28 having a simple cross-sectional shape is made of a rigid material. The skeleton 28 may be formed, for example, in the form of a cut-out sheet metal part. The skeleton 28 includes at least an upper portion 17b of the body of the leg 15 that cooperates with the lower surface 12a of the base 12 (not shown in FIG. 4) when the fixing leg 15 is attached to the base 12. Next, the remaining part 29 of the fixing leg 15 having a complicated cross-sectional shape can be formed, for example, by molding. With this configuration, it is possible to simplify the formation of the fixing device while securing the required rigidity to the fixing device in the event of a collision, for example, in fixing the seat in the vehicle. The skeleton 28 and the remaining portion 29 of the fixing leg 15 are combined using, for example, gluing or other methods that can properly fix the two parts.

  Of course, the third embodiment described above can be combined with any one of the first and second embodiments described above.

  In each of the first to third embodiments, the fixing leg 15 is in a stationary state before being inserted into the fixing opening 14, is moved at the time of insertion, and has a stress in the inserted position. It resists the stress of the adding means 22. After passing through the fixing opening 14, the body of the leg 15 is returned to the same fixed position as the initial rest position by the restoring spring 22.

(Fourth embodiment)
The fourth embodiment will now be described with reference to FIGS. 5a and 5b, which show only the fixing feet 15 and the base 12 that are unique to the fourth embodiment of the invention, but the other component elements will first be described. It is the same as or similar to each described embodiment.

  In the fourth embodiment, the main body of the leg 15 is not helical but has a shape complementary to the shape of the fixing opening 14 and has a longitudinal shape in the direction along the axis (y). I have. Two downwardly extending arms 30 are attached to the cylindrical portion 18 of the leg 15 on both sides. Each arm 30 has a fixing hole 31 to which a wire or blade-shaped spring 20 can be attached at a lower portion 30a. In the embodiment, the fixing hole 31 receives the first end 20a of the spring wire 20 that extends upward and toward the center with respect to the leg 15 as the distance from the body of the leg 15 increases. In the embodiment, two spring wires 20 are symmetrically attached to the main body of the leg 15 with reference to the vertical axis y at the center of the fixing leg, which is the same as the arrangement direction. Each spring wire 20 is configured to be freely rotatable in the fixing hole 31, but may be limited as required.

  The fixing opening 14 differs from the previous embodiment in that it further comprises a carved portion 32 for each of the two spring wires 20 supported by the fixing legs 15.

  When the equipment is installed, when the fixing leg 15 is moved vertically downward and passes through the fixing opening 14, the spring wire 20 is pressed against the main body of the leg 15 and slides so as to slide. It slides in the engraved part 32 provided in the part 14. Since the spring wires 20 are eccentrically arranged on both sides of the vehicle equipment arrangement direction y, the spring wires 20 provide a moment force suitable for rotating the leg 15 about the arrangement axis y. It is. The body of the leg 15 has contact surfaces 15a, 15b which are complementary in shape to the guiding surfaces 13a, 13b of the fixing opening 14, so that the arm 30 passes completely through the fixing opening 14. Until the rotation is performed, rotation about the axis y by the action of the spring wire 20 cannot be performed.

  Once the arm 30 has passed through the fixing opening 14, as shown in FIG. 5 b, the spring wire 20 is retained in the engraved portion 32 and is pressed by the spring wire 20 during the operation of inserting the fixing leg into the base 12. The legs 15 rotate around the axis y. To this effect, as in the above-described embodiment, the base 12 may be provided with a concave portion on its lower surface (not shown) for enabling the play between the leg 15 and the base 12 to be eliminated.

  By doing so, in the fourth embodiment, the fixing leg 15 can rotate between the stationary position and the fixed position that is the same as the insertion position.

  Of course, this fourth embodiment can be combined with the third embodiment described above, which includes a rigid structure and a molded structure.

  In each of the embodiments described above, the fixing of the support device 16 to the vehicle equipment is carried out in a floating manner in order to allow longitudinal and / or lateral play of the fixed position with respect to the equipment of the vehicle. Can be. This makes it possible to adapt the fixing of the equipment to different vehicles having different fixing positions on the chassis.
