Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a seat belt retractor mounting structure for a vehicle.

(Prior Art) In recent years, in order to ensure the safety of passengers of a vehicle, it has become mandatory to wear a seat belt.
This seat belt is retractably stored in a seat belt retractor attached at a proper position on the vehicle body.The seat belt is pulled out from the seat belt retractor and hung on the upper half of the occupant's body. When a heavy load is applied, the drawer is locked to ensure the safety of passengers.

Therefore, a large load is applied to the Sievert retractor at the time of a vehicle collision or the like, and therefore it is necessary to strengthen the mounting structure thereof, and various mounting structures have been conventionally proposed. For example, as disclosed in Japanese Utility Model Laid-Open No. 64-1153, there is a seat belt retractor attached to an opening formed in a cab side inner.

(Problems to be solved by the invention) When the seatbelt retractor mounting structure as in the above-mentioned known example is adopted, the vehicle body rigidity of the seatbelt retractor mounting portion may be insufficient due to the formation of the opening and the like. In such a case, it may be difficult to secure the restraint force on the occupant by the seat belt. As a countermeasure, it is conceivable to use a special reinforcing member, but since there is a concern that the number of parts will increase and the cost will increase, it is possible to prevent a decrease in vehicle body rigidity at the seatbelt retractor attachment portion with a simple configuration. To do so is a technical problem to be solved.

The present invention has been made in view of the above points, and it is an object of the present invention to prevent a decrease in vehicle body rigidity at a seat belt retractor mounting portion.

(Means for Solving the Problems) In the present invention, as means for solving the above problems,
A suspension reinforcement forming a closed cross-section is provided between the upper part of the tire house and the inside of the rear pillar to form an inner panel located on the inner surface side of the vehicle body, while the inner panel has an annular wall portion facing outward at an appropriate position. An opening is formed and the annular wall is joined to the vertical wall of the suspension reinforcement, and the opening formed in the inner panel is provided in the closed cross section formed by the suspension reinforcement. The seat belt retractor is housed so as to be exposed, and the seat belt retractor is fixed to the inner edge of the opening of the inner panel and the suspension reinforcement in a tightened state.

(Operation) In the present invention, the following operations can be obtained by the above means.

That is, a vertical wall of a suspension reinforcement forming an opening having an outward annular wall portion at a rim at a proper position of an inner panel on the inner surface side of a vehicle body and forming a closed cross section with the annular wall portion and the inner panel. The suspension reinforcement and the inner panel are joined at different points by joining the seat belt retractor and the seat reinforcement in the suspension reinforcement, and the seat belt retractor is accommodated in the inner panel opening portion. By fixing the rim and the suspension reinforcement together in the tightened state,
Since the seatbelt retractor mounting part is a part where the rigidity is strengthened regardless of the direction of load application by combining the annular wall part of the inner panel and the vertical wall part of the suspension reinforcement, The binding force will be secured.

(Effect of the Invention) According to the present invention, an opening having an outwardly facing annular wall portion is formed at an appropriate position of the inner panel on the inner surface side of the vehicle body, and a closed cross section is formed together with the annular wall portion and the inner panel. The suspension reinforcement to be formed is joined to the vertical wall portion to join the suspension reinforcement and the inner panel at different points, and the seat belt retractor is housed in the suspension reinforcement. Since the belt retractor is fixed to the rim of the opening of the inner panel and the suspension reinforcement together, the seat belt retractor is attached to the vertical wall of the inner panel and the suspension reinforcement. Irrespective of the direction of load application due to the connection with the parts Since the location is reinforced, the restraint force by the seat belt retractor is secured, and it is possible to prevent deterioration of vehicle rigidity with a simple structure without using special reinforcing members. Has a positive effect.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1 to FIG. 6, the rear part of the vehicle body of the automobile of this embodiment is provided with an inner panel 2 which is located inside the rear fender panel 1 and constitutes an inner side surface of the vehicle body. Is an integrally molded product including a tire house 3, a quarter panel 4, and a rear pillar inner panel 5. Further, in this embodiment, the rear pillar outer panel 6 is also integrally formed on the rear fender panel 1, and the rear pillar outer panel 6 and the rear pillar inner panel 5 constitute a rear pillar 7 having a closed cross-section structure. (See Figure 3). A suspension tower 8 for receiving the load of a suspension device (not shown) is joined to the inner surface of the inner panel 2.

A suspension reinforcement 9 for forming a closed cross section from the tire house 3 to the rear pillar 7 (specifically, the rear pillar inner panel 5) is joined to the outer surface side of the inner panel 2. The suspension reinforcement 9 serves to prevent the suspension tower 8 from falling inward, and has a U-shaped cross section as shown in FIGS. 5 and 6. Then, on the periphery of the suspension reinforcement 9, a lower flange portion 9a that is a joint portion with the tire house 3 and side flange portions 9b and 9b that are a joint portion with the quarter panel 4 are integrally formed. Has been formed. Also,
A recess 9c formed by being recessed toward the inner panel 2 side is formed at a substantially central portion of the suspension reinforcement 9.
The concave portion 9c is fixed to the outer surface of the inner panel 2 by a bolt 10 and a nut 11. Reference numeral 12 is a bolt insertion hole.

An opening 14 is formed in the rear pillar inner panel 5 portion of the inner panel 2, and the seat belt retractor 13 is formed by the suspension reinforcement 9 through the opening 14 to form a closed cross section. It is stored inside. Reference numeral 16 is a seat belt. The mounting bracket 15 of the seat belt retractor 13 is fixed together with the recess 9c of the suspension reinforcement 9 to the inner panel 2 by the bolt 10 and the nut 11. With this configuration, the seat belt retractor
The mounting portion of 13 is a portion where the rigidity is strengthened by the connection of the inner panel 2 and the suspension reinforcement 9, and the deterioration of the vehicle body rigidity at the mounting portion of the seat belt retractor 13 is prevented. . Therefore, the restraint force of the occupant by the seat belt retractor 13 can be sufficiently secured.

Further, in the present embodiment, an outwardly projecting annular wall portion 14a is integrally provided at the rim of the opening portion 14, and the suspension reinforcement 9 is attached to the annular wall portion 14a. The vertical wall portions 9d, 9d are joined together. With this configuration, the suspension reinforcement 9 has the joint portions between the side flange portions 9b, 9b and the inner panel 2, the annular wall portion 14a at the rim of the opening 14 and the vertical wall portion 9d of the suspension reinforcement 9. It will be joined to the inner panel 2 at a position where the direction of the joint with 9 and 9d is different, regardless of the direction of the load applied to the seatbelt retractor 13, the seatbelt retractor 13 mounting portion. Therefore, the rigidity is secured.

The present invention is not limited to the configuration of the above embodiment, and it is needless to say that the design can be changed as appropriate without departing from the gist of the present invention.
