Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat mounting structure, and particularly to a mounting structure to a vehicle body side panel.

As a conventional structure for attaching a seat to a vehicle body side panel, there is, for example, one shown in FIGS. 1 and 2. That is, reference numeral 1 is a panel on the vehicle body side, and a second cross member 2 protrudes from a floor panel 3. Reference numeral 4 is the seat, which includes a seat body 5 and a backrest 6.
and a slide device 7. Reference numeral 8 denotes a sound insulating material placed along the vehicle body side panel, and a sound insulating material main body 11 is formed by a base cloth 9 and a pile 10, and a through hole 12 is formed in this main body 11. A nut 13 is fixed to the periphery of the through hole 14 of the second cross member 2 by welding or the like. The slide device 7 has a movable rail 15 fixed to the seat body 5 and a fixed rail 16 fixed to the vehicle body side panel 1, and a seat fixing bracket 17 is provided to protrude from the fixed rail 16. ing. The structure is such that a bolt 19 inserted into a through hole 18 of this bracket 17 is screwed onto the nut 13.

However, in the mounting structure of such a seat, since the sound insulating material 8 is interposed between the seat fixing bracket 17 and the vehicle body side panel 1, the sound insulating material 8 is inserted while the seat is in use. may deteriorate over time and become thinner, resulting in bolt loosening.

For this reason, as shown in Japanese Utility Model Application No. 53-70021, by forming a ring-shaped protrusion from the seat mounting bracket and directly applying the ring-shaped protrusion to the upper surface of the floor panel, the fastening force of the bolt can be directly applied. A technique for transmitting information to Natsuto has been disclosed. It is true that this invention eliminates the problems of the conventional example mentioned above.

However, since the height of the ring-shaped protruding edge that protrudes from the seat mounting bracket remains the same as long as the seat mounting bracket is shared, the height of the ring-shaped protrusion that protrudes from the seat mounting bracket is the same, so the height of the ring-shaped protrusion that protrudes from the seat mounting bracket is the same, so the height of the ring-shaped protrusion that protrudes from the seat mounting bracket is the same as long as the seat mounting bracket is shared. Not compatible with the specified carpet. In other words, relatively cheap cars usually have thin carpets, and expensive cars usually have thick carpets, but if you decide the height of the ring-shaped ridge according to the thickest carpet, it will be thinner than that. In the case of carpet, the ring-shaped edge may be visible, the through-hole in the carpet around the ring-shaped edge may be exposed, or even the shoes may be damaged by hitting the rough surface of the seat mounting bracket that is floating above the carpet. There is a fear. If the height of the ring-shaped ridge is determined according to the thinnest carpet, if the carpet is thicker than that, the edge of the ring-shaped ridge will not touch the top surface of the floor panel and will rise up. This does not go beyond the scope of the prior art.

In view of such prior art, the present invention enables a seat to be reliably fixed to a vehicle body side panel even if there is a difference in the thickness specifications of the carpet, and also prevents the ring-shaped ridge from being visible or the area around the ring-shaped ridge to be fixed. To provide a seat mounting structure in which there is no risk of exposing a through hole in the carpet or damaging the shoes by hitting the rough surface of a seat mounting bracket floating from the carpet.

For this reason, in the present invention, as a seat mounting structure, a nut is fixed to the lower surface of the peripheral edge of the through hole in the vehicle body side panel, and a seat fixing bracket is installed with a sound insulating material placed along the upper surface of the vehicle body side panel. Arranged,
In a seat mounting structure in which a bolt inserted into a through hole of the seat fixing bracket and a through hole of the sound insulating material is screwed to the nut, the through hole of the sound insulating material has a thickness approximately equal to the thickness of the sound insulating material. A spacer having the same thickness and having a through hole through which the bolt can be inserted is removably arranged, and the base fabric of the sound insulating material is supported from below on the circumferential surface of the spacer. A retainer comprising a first member having a hat-shaped cross section and a second member having an inverted hat-shaped cross section, which is screwed onto the first member and supports a pile of sound insulating material from above to prevent the pipe from going to the upper surface of the spacer. It is characterized by the fact that it adheres to the following.

Therefore, no matter what thickness the carpet is, by replacing only the inexpensive spacer according to the thickness, the seat fixing bracket can be securely fixed to the car body side panel. Furthermore, at this time, these mounting members will not be exposed. Further, since no carpet pile is interposed between the surface of the bracket for fixing the criminal record seat and the surface of the spacer, it is possible to securely fix the seat and prevent incomplete fastening and loosening.

Next, one embodiment of the present invention will be described using the drawings of FIGS. 3 and 4.

In the figure, reference numeral 30 denotes a sound insulating material placed along the top of the vehicle body panel 1, and the sound insulating material 30 is the sound insulating material main body 11.
, a spacer 31 inserted into the through hole 12 of the sound insulation material main body 11 , and a spacer 31 that is firmly fixed to the circumferential surface 32 of the spacer 31 by means such as adhesive, and the sound insulation material main body 11
The seat fixing bracket 17, the spacer 31, the retainer 33, and the vehicle body side panel 1 are directly fixed with bolts 19. The spacer 31 desirably has a thickness that is approximately equal to the thickness of the pile 10 of the sound insulating material body 11 in a raised state, and is made of a metal material such as iron.

Further, the retainer 33 is screwed into a first member 34 having a hat-shaped cross section that supports the base cloth 9 of the sound insulation material body 11 from below, and also supports the pile 10 of the sound insulation material body 11 from above. Support from
It consists of a second member 35 having an inverted hat-like cross section that prevents the pile 10 from moving to the upper surface of the retainer 33 and the spacer 31, and both members 34,
35 may be made of synthetic resin or metal. 1st
It is desirable that the second member 35 has a retaining function relative to the member 34.

As described above, according to the present invention, as a seat mounting structure, a nut is fixed to the lower surface of the peripheral edge of the through hole of the vehicle body side panel, and a sound insulating material is attached along the upper surface of the vehicle body side panel. In the seat mounting structure, a seat fixing bracket is arranged with a seat fixing bracket interposed therebetween, and a port inserted into a through hole of the seat fixing bracket and a through hole of the sound insulating material is screwed to the nut. A spacer having a thickness substantially the same as that of the sound insulating material and having a through hole through which the port can be freely inserted is removably arranged in the through hole, and a spacer is provided on the circumferential surface of the spacer. a first member having a hat-shaped cross section that supports the base fabric of the sound insulating material from below; and a first member that is screwed to the first member and supports the pile of the sound insulating material from above so that the pile does not reach the upper surface of the spacer. Since it is characterized by firmly holding a retainer made of a blocked second member having an inverted hat-like cross section, no matter what thickness the carpet is, only an inexpensive spacer can be used to match the thickness. If replaced, the seat fixing bracket can be securely fixed to the vehicle body side panel, and in this case, these mounting members will not be exposed, and the surface of the seat fixing bracket and the spacer will be Since there is no carpet pile interposed between the sheet and the surface, it is securely fixed and prevents imperfections or loosening during fastening, so even if there are differences in the thickness specifications of the carpet, the sheet can be securely fixed to the vehicle body side panel, and the ring-shaped ridge can be seen,
Not only will there be no risk of exposing the through holes in the carpet around the ring-shaped protrusion, or even damaging your shoes by hitting the bumpy surface of the seat mounting bracket that is floating above the carpet, but it will also prevent you from tightening the seat mounting bolts. This is a practical invention that has the remarkable effect of preventing torque loosening.
