[Modes for carrying out the invention]

[0012] <1. Embodiments> The following describes a seat position adjustment device 10 according to one embodiment of the present invention, with reference to the drawings.

[0013] Figure 1 is a schematic diagram showing the relationship between the rear seat 100 and the seat mounting surface 200 of an automobile before the seat position adjuster 10 of the embodiment is installed. The seat position adjuster 10 is used to adjust the position of the seat in the longitudinal direction of the automobile. In a typical example, the seat position adjuster 10 is used to adjust the position of the rear seat 100 relative to the seat mounting surface 200 inside the automobile to the rear.

[0014] The front portion of the rear seat 100 is fixed to the seat mounting surface 200 via a connector 300. The rear seat 100 and the seat mounting surface 200 are fixed together, for example, by four connectors 300 arranged along the width direction of the vehicle. The rear seat 100 is positioned at a predetermined angle of inclination with respect to the seat mounting surface 200. The predetermined angle is, for example, 13°.

[0015] The connector 300 has a first part 310 and a second part 320. The first part 310 and the second part 320 are connected at their front portions by a connecting mechanism such as a hinge. The second part 320 is rotatable relative to the first part 310. The first part 310 is fixed to the seat mounting surface 200. The second part 320 is fixed to the bottom surface of the seat surface of the rear seat 100. The second part 320 and the rear seat 100 are fixed together by bolts.

[0016] The rear portion of the rear seat 100 is fixed to the seat mounting surface 200 via lock hinges (not shown) that are fixed to the seat mounting surface 200. For example, the rear portion of the rear seat 100 is fixed to the seat mounting surface 200 by four lock hinges arranged along the width direction of the vehicle. Each of the four lock hinges is fixed to the seat mounting surface 200 by two bolts. In other words, the four lock hinges and the seat mounting surface 200 are fixed together by eight bolts.

[0017] The seat position adjuster 10 comprises a first adjuster 11 (see Figure 2) and a second adjuster 12 (see Figure 3).

[0018] The first adjuster 11 is configured to be attached to the front side of the rear seat 100. The first adjuster 11 has a first plate 21 and a first through-hole 22.

[0019] The first plate 21 is made of a metal material. The metal material constituting the first plate 21 is, for example, iron. The metal material constituting the first plate 21 may be an alloy containing a plurality of metals. The first through-hole 22 is a hole penetrating the first plate 21. The first through-hole 22 has two first-type through-holes 22A and two second-type through-holes 22B. The two first-type through-holes 22A and the two second-type through-holes 22B are arranged side by side along the longitudinal direction of the first plate 21.

[0020] The first-type through-hole 22A is a hole into which a bolt for connecting with the second part 320 of the connector 300 is inserted. The second-type through-hole 22B is a hole into which a bolt for connecting with the bottom surface of the seating surface of the rear seat 100 is inserted.

[0021] The thickness TA of the first plate 21 can be arbitrarily selected. From the viewpoint of enhancing rigidity, the thickness TA is preferably 5 mm or more. The width WA of the first plate 21 can be arbitrarily selected. From the viewpoint of enhancing rigidity, the width WA is preferably 5 cm or more. When the thickness TA varies depending on the part, the thickness TA is, for example, the maximum thickness. When the width WA varies depending on the part, the width WA is, for example, the maximum width.

[0022] The second adjuster 12 is configured to be attached to the seat arrangement surface 200 facing the rear side of the rear seat 100. The second adjuster 12 is arranged to correspond to the bolt holes to which eight bolts for fixing the four lock hinges and the seat arrangement surface 200 are attached. That is, eight second adjusters 12 are arranged. The second adjuster 12 has a second plate 31, a second through-hole 32, and a shaft 33.

[0023] The second plate 31 is made of a metallic material. The metallic material constituting the second plate 31 is, for example, iron. The metallic material constituting the second plate 31 may also be an alloy containing multiple metals. The second through hole 32 is a hole that penetrates the second plate 31. The second through hole 32 is a hole into which a bolt for fixing to the sheet placement surface 200 is inserted.

[0024] A locking hinge is inserted into the shaft 33. A threaded portion 33A is formed on at least a part of the shaft 33. The shaft 33 and the locking hinge are fixed together by fitting a nut onto the shaft 33 while the locking hinge is inserted into the shaft 33. One end of the shaft 33 is inserted into a recess 31A formed in the second plate 31. The recess 31A is a recess that does not penetrate the second plate 31. The method of fixing the shaft 33 to the second plate 31 can be arbitrarily selected. For example, the method of fixing the shaft 33 to the second plate 31 can be welding, press-fitting, bonding, or crimping.

[0025] The thickness TB of the second plate 31 can be arbitrarily selected. It is preferable that the thickness TB is thinner than the thickness TA. In other words, it is preferable that the thickness TA is thicker than the thickness TB. The width WB of the second plate 31 can be arbitrarily selected. It is preferable that the width WB is narrower than the width WA. In other words, it is preferable that the width WA is wider than the width WB. If the thickness TB differs depending on the part, the thickness TB is, for example, the maximum thickness. If the width WB differs depending on the part, the width WB is, for example, the maximum width.

[0026] An example of a method for adjusting the position of the rear seat 100 to the rear using a seat position adjustment device 10 (hereinafter referred to as the "seat position adjustment method") will be described below. The seat position adjustment method includes the first, second, third, fourth, fifth, sixth, and seventh steps.

[0027] In the first step, the rear seat 100 is tilted forward, and the bolts securing the second part 320 of the connector 300 to the rear seat 100 are removed.

[0028] In the second step, the first type through hole 22A of the first adjuster 11 is connected to the second part 320 of the connector 300 by a bolt. The bolt used in the second step may be the bolt removed in the first step, or it may be a different bolt from the one removed in the first step.

[0029] In the third step, the second type through hole 22B of the first adjuster 11 and the rear seat 100 are fixed together with a bolt. The bolt used in the third step may be a different bolt from the one removed in the first step, or it may be the same bolt that was removed in the first step.

[0030] In the fourth step, remove the eight bolts that secure the four locking hinges to the seat mounting surface 200.

[0031] In the fifth step, the second adjustment tool 12 is positioned so that its second through-hole 32 corresponds to each of the eight bolt holes, and the bolts are inserted to fix the second adjustment tool 12 to the seat placement surface 200. The bolts used in the fifth step may be the bolts removed in the fourth step, or they may be different bolts from those removed in the fourth step.

[0032] In the sixth step, the lock hinges are inserted onto the shafts 33 of the second adjusters 12, and nuts are fitted onto the shafts 33 to secure the four lock hinges and the eight second adjusters 12.

[0033] In the seventh step, the rear seat 100 is tilted toward the seat mounting surface 200, and the rear seat 100 and the seat mounting surface 200 are fixed together via a locking hinge. Upon completion of the seventh step, the position of the rear seat 100 is adjusted to be further rearward than the initial position shown in Figure 1, as shown in Figure 4. When the seat position adjustment device 10 is installed, the rear portion of the rear seat 100 is higher than the initial position by the thickness TB of the second adjustment device 12. Therefore, when the seat position adjustment device 10 is installed, the inclination angle of the rear seat 100 relative to the seat mounting surface 200 is gentler than in the initial position. The inclination angle of the rear seat 100 relative to the seat mounting surface 200 when the seat position adjustment device 10 is installed is, for example, 9°.

[0034] <2. Features> The seat position adjuster 10 comprises a first adjuster 11 and a second adjuster 12. Therefore, the seat position adjuster 10 is easily constructed.

[0035] The above embodiments are examples of possible forms of the seat position adjuster according to the present invention and are not intended to limit its form. The seat position adjuster according to the present invention may take forms different from those illustrated in the embodiments. One example is a form in which some of the components of the embodiments are replaced, modified, or omitted, or a form in which new components are added to the embodiments. [Explanation of Symbols]
