  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  1 to 3-2, this embodiment is an example in which a port (described later) of the present invention is adopted in a front seat for an automobile (hereinafter, simply referred to as a seat). In the seat, the seat 1 is a combination of a seat cushion and a seat back (not shown), and the seat back includes a seat frame 2, left and right side frames 3 and 3, an upper frame 4, and a lower frame (no reference numeral). It is composed of a frame. The seat frame 2 may have the frame shape shown in FIGS. 1-1 and 2, the pipe shape shown in FIGS. 3-1 and 3-2, or a panel shape, although not shown.

  Square brackets 5 and 5 (deformed brackets 50 and 50) are inserted and supported in the fitting holes 400 and 400 of the upper frame 4. As shown in FIGS. 8 to 9, the brackets 5 and 50 are fitted and supported in a pair of fitting holes 400 in the horizontal portion 401 of the upper frame 4. The bracket 5 includes a rear side 5a or a front side 5b, which is the forward direction of the vehicle (front side in FIG. 1), and a left side 5c and a right side 5d in the vehicle width direction (left and right direction in FIG. 1), which are not shown. In principle, it has a rectangular shape when seen in a plan view. First, in the first example, in the example shown in FIG. 8, the bracket 5 has a rectangular shape, which is useful for improving accuracy or stability of operating load. Clinch cutouts 500 in a pair form (opposing form) are formed from the rear side 5a and / or the front side 5b, or on either of the left and right sides 5c, 5d of the vehicle. The notch 500 is, for example, a combination of three mountain portions 500a (mounting portion 500a1), an inclined portion 500b (inclining portion 500b1) connecting the mountain portions 500a, and straight portions 500c at both ends (straight line receiving portion 500c1). It has a structure, and the linear portions 500c have different phases. A plurality of caulking processes 501 are provided in the clinch notch 500 formed at the connecting portion of the mountain portion 500a and the mountain receiving portion 500a1 and / or the connecting portion of the inclined portion 500b and the inclined receiving portion 500b1. As described above, the reason why the clinch notch 500 and the caulking process 501 are performed on the plate material after forming the bracket 5, for example, is to improve the strength and prevent backlash. In the example shown in FIGS. 9 to 9-1 to 9-4 as the next second example, the bracket 50 has an irregular shape and is viewed in a plan view. For example, the forward direction of the vehicle (the front direction in FIG. 1). It has a shape that is inclined from one end side (left side 50c) to the other end side (right side 50d), and the other end side projects in the forward direction in the forward direction (left side 50c <right side 50d). The bracket 50 includes a left side 50c and a right side 50d, which are framed by these and the rear front sides 50a and 50b. In this, one of the widths of the rear front sides 50a and 50b (the width direction of the vehicle) is , By adopting a long structure, it exhibits an irregular shape. The advantage of this irregular shape is that it facilitates the insertion (insertion) of the support (the structure of which will be described later) (eliminates an insertion error), improves accuracy, and stabilizes the operating load. A clinch notch 5000 having a deformed shape that forms a pair shape (opposing shape) is formed on either the front side 50a or the rear side 50b. The clinch notch 5000 has, for example, a combined structure of three crests 5000a (mountain receiving part 5000a1) and a straight part 5000c (straight line receiving part 5000c1) connecting the crests 5000a, and the straight part 5000c has the same phase. . Further, the bracket 50 has a left side 50c and a right side 50d, which are framed by these and the rear front sides 50a and 50b. A plurality of caulking processes 50001 are provided in the clinch notch 5000 formed at the connecting portion between the mountain portion 5000a and the mountain receiving portion 5000a1 and / or at the connecting portion between the linear portion 5000c and the linear receiving portion 5000c1. As described above, the reason why the clinch notch 5000 and the caulking processing 50001 are performed on the plate material after forming the bracket 50 is to improve strength and / or accuracy and prevent backlash.

The clinch notch 500 and the caulking process 501 of the square bracket 5 described above can be replaced with the clinch notch portion 5000 and the caulking process 50001 of the bracket 50 having an irregular shape. Similarly, the clinch cutout portion 5000 and the caulking processing 50001 of the irregularly shaped bracket 50 can be replaced with the clinch cutout portion 500 and the caulking processing 501 of the rectangular bracket 5.
The irregularly shaped support 100 shown in FIGS. 4-1 to 7-2 (the support 100 includes a rear side 100-1, a front side 100-2, a left side 100-3, a right side 100-4, and an inclined surface 100-5. , Flat surface 100-6) has a through hole 11. The head 100a has an insertion hole 12 for an operation button (not shown). The neck portion 100b is provided with a plate-shaped elastic piece 13. The upper end 50e of the bracket 50 is attached to the elastic piece 13. Elastic piece 13 By this attachment, the impact generated in the support 100 is mitigated (prevention of rattling between the bracket 50 and the support 100), and the rattling noise which is considered to be caused thereby is avoided. Furthermore, it is possible to eliminate the impact propagation to the headrest support 100 and the like. The elastic piece 13 is separated from the neck portion 100b by a notch portion 100b2 formed on the front side 100b1 of the neck portion 100b of the support 100. Therefore, the elastic piece 13 has flexibility. That is, at least the elastic piece 13 is formed so as to be flexible in the vertical direction, and at least the free end 13a of the elastic piece 13 is projected from the front side 100b1 of the neck portion 100. In this way, the free end 13a of the elastic piece 13 is formed so as to extend outward from the outer peripheral surface of the neck portion 100b. Then, at least the free end 13a that is extendedly formed is attached to and supported by the upper end 50e of the bracket 50 provided on the seat frame 2 (upper frame 4). Further, the protrusion 14 of the neck portion 100b (the rear side 100-1 of the support 100) is inserted and locked in the notch 50g provided in the rear side 50b of the bracket 50. The vertical dimension X of the neck portion 100b ensures a relationship of vertical dimension X <vertical dimension X1 of the conventional example neck portion with respect to the vertical dimension X1 of the conventional example neck portion shown in FIG. 10, and shortens the vertical dimension of the support 100. At least, it contributes to weight reduction. Next, on the body part 100c (the left side 100-3 and the right side 100-4 of the support 100), the latching pieces 15 and 16 are outwardly bulged and formed in a valve shape. The reference numerals 15 and 16 are inserted and locked in the cutout windows 5002 and 5003 of the bracket 50. Further, it contributes to the integration of the bracket 50 and the support 100 shown in FIG. The hooking piece 15 on the front side 100-2 has an inclined shape because the front side 100-2 is the inclined surface 100-5. That is, for example, in FIGS. 4-1 and 4-2, the arrow Y direction (the front direction of the front side 100-2, the seating direction of the seat) bulges. As shown in the drawing, the right leg (leg portion 15b) bulges toward the front with respect to the left leg (leg portion 15a) and is elongated downward, and has a deformed fitting hole 400 in the upper frame 4. Intended to match. Further, in the latching piece 16 on the rear side 100-1, the rear side 100-1 is the flat surface 100-6, and for example, in FIG. 4-3, the arrow Z direction is the flat surface 100-6. As shown in the drawing, the right leg (right leg) and the left leg (left leg) have the same correspondence, and have the same bulge, downward length, and the like. It is intended to match the -6 mating hole 400. The bracket 5 shown in FIG. 8 has a rectangular shape, and a support (not shown) inserted into this bracket 5 has a rectangular end surface. This rectangular support (not shown) conforms to the irregular-shaped support 100 described above.

  In the rectangular shape support 10 shown in FIG. 8, the component name of the irregularly shaped support 100 is shown, and the numeral of the reference numeral lowers the digit. For example, the latch pieces 15 and 16 are inserted and formed in the cutout windows 502 and 503 of the bracket 5. Further, the notch is 5 g and the clinch notch is 500.

  It should be noted that the irregularly shaped support 100 is provided with a padding portion. That is, starting from the left side 100-3 of the front side 100-2 of the neck portion 100b, the meat buildup successively competes toward the right side 100-4, and the right side 100-4 becomes the highest meat buildup (hereinafter the same. ). For example, starting from the left side 100-3 of the front side 100-2 of the body portion 100c, the meat buildup sequentially competes toward the right side 100-4, and the right side 100-4 is the highest meat buildup (the same applies hereinafter. is there). The same applies to the latching piece 15. Therefore, the leg portions 15a and 15b of the latching piece 15 have different lengths, and there is a dimensional relationship of leg portion 15a <leg portion 15b. This corresponds to the bulging dimension having a dimensional relationship of leg 15a <leg 15b. In this example, the description is omitted in view of the irregular shape, but the related parts also have the same built-up structure. In the rectangular support 10, there is no bulging padding.

  10-1 and 102, the bracket mounting portion 200 formed by crushing the seat frame 2, the clinch notch 5000, and the caulking 5001 are on the forward side of the vehicle. Then, the brackets 5 and 50 (hereinafter referred to as 5 here) are welded 18 and fixed to the bracket mounting portion 200. The weld 18 is a crushed piece of the seat frame 2 (inner peripheral surface of the fitting hole 400) and the left and right sides 50d and 50e (corresponding to side surfaces) of the bracket 50. The length of the weld 18 is shown as an example in FIG. 10-2, and is D + α with respect to the crushing length D.

  11-1 and 11-2 are the same as FIG. 10-1 etc., but the clinch notch 5000 and the caulking processing 5001 are on the backward side of the vehicle. Others are similar to those shown in FIG.

  FIG. 12 shows a preferable example in which brackets 50 of different shapes are attached to the seat frame 2 using pipes, respectively. For example, (a) is a center 201 in the transverse direction A of the seat frame 2. 6A to 6C are schematic plan views in which the bracket 50 is welded and fixed to the bracket mounting portion 200 that has been crushed B. In this example, gaps C and C ′ (hereinafter referred to as C) are formed between, for example, both left and right side surfaces 200c and 200d of the bracket mounting portion 200 and, for example, both left and right side surfaces 50c and 50d of the bracket 50. In view of the formation, the convex portion 5004 is formed on the left side 50c of the bracket 50 at least for the purpose of covering the gap C between the left side surface 200c of the bracket mounting portion 200 and both left side surfaces 50c of the bracket 50. The convex portion 5004 (the protruding position can be changed) is effective for protecting the gap C, reducing the amount of welding (welding member), or improving the welding strength. In this example, for example, on the left and right sides 200c, 200d (5c, 5d) and / or the rear side 200b of the bracket attachment part 200 (bracket 5), for example, the upper side (upper end 5e) in the vertical direction, and / or The lower side (lower end 5f) is welded 18. In this embodiment, although not shown, it is possible to adopt the bracket 50 having an irregular shape with respect to the seat frame 2 made of steel, and the same effect can be expected. Alternatively, the same applies to the square bracket 5. Next, (B) is a schematic plan view in which the bracket 2 is welded and fixed to the crushed bracket mounting portion 2000 up to the front side (front side) of the center 201 in the transverse direction C of the seat frame 2, its configuration and effects, etc. All conform to (a) above. Further, (C) is a schematic plan view in which the bracket 2 is welded and fixed to the crushed bracket mounting portion 200 in the transverse direction C of the seat frame 2 to the rear side (back surface side) of the center 201, its configuration and effect. Etc. are all in accordance with (a) above.

  FIG. 13 is a diagram for schematically explaining the relationship between the elastic piece 13 and the main body 100-7 of the support 100. FIG. 13A shows a basic body in which the elastic piece 13 has a uniform width. It is the way of thinking formed in. In addition, (b) is a form in which the upper part descends toward the tip and the lower part or the flat part has a relationship of B1 / B2, which is an optimum form and can contribute to constant stress (d). Please refer to the chart. Further, (c) is another example of (b), and the same effect as (b) can be expected. L in the drawing indicates the cantilever length.

  Note that FIG. 14 shows the bracket 5 having a normal shape.
