Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to an improvement of a rear panel inner structure having a seat belt retractor in a passenger vehicle.

(Prior Art) A conventional rear panel inner structure will be described with reference to FIG. 4.

In Fig. 4, 1 is the rear panel outer;
This rear panel outer 1 forms a body extending from a rear pillar to a rear wheel house in a passenger vehicle.

Inside this rear panel outer 1, a rear panel inner 3 is provided with a certain space 2. That is, by bending the lower edge of the rear panel outer 1, the lower edge of the rear panel inner 3 is caulked and connected. This rear panel inner 3 is composed of a rear panel inner upper 4 at the upper part and a rear panel inner lower 5 at the lower part, and the lower edge of the rear panel inner upper 4 and the upper edge of the rear panel inner lower 5 are joined by welding. are doing. This rear panel inner lower 5 has a lower portion bent to form a wheel house outer portion 6, and the above-mentioned space 2 is formed in the upper portion of this wheel house outer portion 6.

Further, an inner wheel house 7 has its upper edge joined to the middle part of the rear panel inner lower 5 by welding.

A rectangular opening 8 is connected between the upper part of the joining part of the wheel house inner 7 of the rear panel inner lower 5 and the joining part of the rear panel inner upper 4 by burring. moreover,
A plurality of machined holes (not shown) are provided around the opening 8 to be used when assembling the vehicle body. This hole is sealed with a rubber part when the car body is completed.

A seatbelt retractor 10 for a rear seat is provided in the space 2 of the opening 8, which is covered with a pad 9 made of rubber, for example, on all sides except for one side facing the inside of the vehicle. This pad 9 is intended to prevent noise from the outside from entering from the vicinity of the attachment portion of the seat belt retractor 10 via a trunk room (not shown) or the like while the vehicle is running.

In the conventional rear panel inner structure configured as described above, the rear panel inner upper 4 is plate-shaped, and an opening 8 is provided in the upper part of the rear panel inner lower 5, so that the inner side of the rear panel inner upper 4 If an impact force is applied to a seat belt waving guide (not shown) provided in the rear panel inner 3, there is a risk that the rear panel inner 3 will be damaged or deformed.

(Problems to be solved by the invention) As explained above, in the conventional rear panel inner structure, the parts that require strength are formed in a plate shape, and in addition, an opening for attaching a seatbelt retractor in the rear seat is provided. Because of this, the strength against impact loads was low.

This idea was created in view of the above circumstances, and it not only improves the strength of the rear panel inner against the impact force from the rear seat belt, but also makes it possible to obtain a soundproofing effect without using the conventional soundproofing parts. The purpose is to provide a rear panel inner structure that is possible.

[Structure of the idea]

(Means and effects for solving the problem) This invention has a rear panel inner structure composed of a rear panel inner top and a rear panel inner lower, which has a hat-shaped cross section at the lower part of the rear panel inner top. A bulkhead projecting outward is integrally provided, a peripheral edge of the bulkhead is fixed to the inner lower of the rear panel, and an opening is provided on the inner surface of the inner lower of the rear panel to communicate the inside of the bulkhead with the passenger compartment side, By providing a seat belt retractor in the space surrounded by the bulkhead, the rear panel inner structure improves the strength of the rear panel inner and provides a soundproofing effect without using a soundproofing pad.

(Embodiment) An embodiment of this invention will be described below with reference to FIGS. 1 to 3.

In FIG. 2, 11 is a rear panel inner. This rear panel inner 11 is composed of a rear panel inner upper 12 and a rear panel inner lower 13.

The upper part of the rear panel inner upper 12 is formed into a plate shape, and a bulk head 14 having a hat-shaped cross section is provided at the lower part thereof to protrude outward. That is, a bulk head 14 is provided protruding from a rear panel outer 20, which will be described later.

Further, as shown in FIG. 1, the upper edge of the rear panel inner lower 13 is joined to the upper part of the bulkhead 14 of the rear panel inner upper 12 by welding. A rectangular opening 15 is provided in the upper side surface of the rear panel inner lower 13 by burring from the passenger compartment side. Also, similarly machined holes 15a are provided around the opening 15. These machined holes 15a are for welding work when assembling the vehicle body. Furthermore, the opening 15
The lower part of the wheel housing is bent to form a wheel house outer section 16. The peripheral edge 17 of the bulkhead 14 is connected to the outer surface of the rear panel inner lower 13 by welding. In other words, the bulkhead 1 can be opened from the opening 15.
A communicating space is provided within 4. All parts of the bulkhead 14 except for the opening 15 are sealed to form a space 18.

A seatbelt retractor 19 for a rear seat is provided in this space 18 so as not to protrude into the vehicle interior, as shown in FIG.

Further, at the lower edge of the rear panel inner lower 13, a rear panel outer 2 forming the body of the vehicle is provided.
The lower edges of 0 are bent and caulked together.

The upper edge of the inner wheel house 21 is joined to the middle part of the rear panel inner lower 13 by welding. Furthermore, the machined holes 15a of the rear panel inner lower 13 are each sealed by rubber parts 22 that are engaged with their elastic force.

With the above-described configuration, it is possible to prevent noise from the trunk room 23 and the like in FIG. 3 from entering the vehicle interior. In other words,
By providing the bulkhead 14, a soundproofing effect can be obtained without attaching a pad to the seatbelt retractor 19, which conventionally required a soundproofing pad.

Further, by providing the bulkhead 14, the strength of the rear panel inner 11 against impact loads from the rear seat belt can be significantly improved.

Note that this invention is not limited to the above embodiment. For example, the joining structure of each part is mostly by welding, but it is not limited to this, and any structure can be used as long as it has the strength to construct the vehicle body.

[Effects of the invention] As explained above, according to this invention, by providing a bulkhead on the rear panel inner, it is possible to improve the strength of the rear panel inner against impact loads from the rear seat belt, and it is possible to improve the strength of the rear panel inner against impact loads from the rear seat belt. To provide a rear panel inner structure capable of enhancing the soundproofing effect in a vehicle interior without using soundproofing parts used on the outer surface.
