Description

The present invention relates to a vehicle body structure around a rear seat back (hereinafter, simply referred to as "vehicle body structure").

<Prior Art> As shown in FIG. 3, a conventional vehicle body structure has a seat back center 1a in the middle and seat back sides 1b on both left and right sides.
And the rear seat back 1 formed by connecting the respective members of the lower seat back lower 1c is arranged so as to hang the end of the seat back side 1b on the wheel house inner 2 over the entire vehicle width in the vehicle width direction, This rear seat back 1 forms a boundary between a trunk room (not shown) and a passenger compartment together with a parcel 3 connected to an upper end portion of the rear seat back 1, and further, a rear shock absorber bracket is provided at a rear part of the rear seat back 1, that is, a trunk room side. 4 is symmetrically provided. Further, the rear seat back 1 is provided with a plurality of through holes for passing the harness 5 and the seat belt 6, and the through holes are provided with a sealing member 7 such as urethane sponge. still,
Since the body structure is symmetrical, only half is shown in the figure. (See Japanese Utility Model Laid-Open No. 62-192952) <Problems to be Solved by the Invention> However, in the case of such a vehicle body structure, since the rear seat back 1 itself does not have that much sound insulation, the outside from the trunk room A side The sound was not effectively shielded, and there was an insufficient point regarding the quietness in the passenger compartment B.

Further, in such a vehicle body structure, it is necessary to take measures such as increasing the number of welding spots or adding some kind of reinforcing member in order to secure the strength of the rear shock absorber bracket 4, particularly the strength against the road surface thrust. It was

Therefore, an object of the present invention is to provide a vehicle body structure capable of insulating the external sound from the trunk room side and reinforcing the rear shock absorber bracket all at once.

<Means for Solving the Problems> In order to achieve such an object, in the front and rear positions corresponding to the rear shock absorber bracket in the trunk,
A substantially vertical iron partition wall having a height similar to that of the rear seat back is provided over the entire width direction of the vehicle, and the partition wall is bent backward from the upper end of the partition wall so as to face the parcel integrally with the upper partition wall. In addition, the side end portion of the partition wall is fixed to the rear shock absorber bracket from the substantially front-rear center portion of the vehicle to the vehicle body side portion, and the rear end portion of the upper partition wall is fixed to the rear waist portion.

<Operation> According to such a vehicle body structure, the iron partition wall having high sound insulation effectively shields the external sound from the trunk room side to improve the quietness of the passenger compartment, and the partition wall having such a function is provided. At the same time, the reinforcement of the rear shock absorber bracket works as if a large reinforcing flange was provided, and the strength of the upper surface of the rear shock absorber bracket against the road surface thrust is greatly improved. Therefore, according to this vehicle body structure, at the same time as improving the quietness of the vehicle interior, the conventional reinforcement processing of the rear shock absorber bracket becomes unnecessary, which is a great advantage.

<Examples> Examples of the vehicle body structure according to the present invention will be described below with reference to the drawings. In the following description, the parts common to the above-mentioned conventional example and the parts common to the respective examples will be denoted by the same reference numerals, and redundant description will be omitted.

In this vehicle body structure, the rear shock absorber bracket 4 in the trunk room A behind the rear seat back 1 is used.
A substantially vertical partition wall 10 is provided at a position corresponding to
There is an appropriate gap between the partition wall 10 and the rear seat back 1.

The partition wall 10 is for effectively insulating external sound from the trunk room A side, is made of iron having high sound insulation, and has a height according to the height of the rear seat back 1 and the entire surface in the vehicle width direction. This partition wall
Reference numeral 10 integrally has an upper surface partition wall 10e which is bent backward from the upper end and faces the parcel 3.

Further, the connection flange 11 is bent around the periphery of the partition wall 10.
Through the flange 11, the side end portion of the partition wall 10 is formed from the front and rear central portions of the rear shock absorber bracket 4 (the front and rear central portions of the upper and side surfaces) and the surface of the wheel house inner 2. , Are welded (fixed) to adjacent side portions of the vehicle body. Further, the flange 11 at the lower end of the partition wall 10 is also welded to the rear floor 12. In addition, the rear end portion of the upper partition wall 10e is welded (fixed) to the closed waist rear waist portion 15 formed along the vehicle width direction.

In this way, by fixing the ends of the partition wall 10,
In particular, the rear shock absorber bracket 4 is in a state in which a large reinforcing flange is formed on the surface in an orthogonal state, and is in a state of being strongly reinforced against the road surface thrust force.

A space S is formed in a portion surrounded by the rear seat back 1 and the partition wall 10. The space S is effectively used as a storage place for various electronic units 13, 14 and the like. By arranging various electronic units 13, 14 etc. in S in an integrated manner, the harness path is also simplified.

<Effects of the Invention> The vehicle body structure according to the present invention is, as described above,
An iron partition wall having high sound insulation is provided at the rear portion of the rear seat back at a height according to the height of the rear seat back and over the entire width direction of the vehicle, and the side end portion of this partition wall is a rear shock absorber bracket vehicle. Since it is fixed to the front and rear central part, the external sound from the trunk room side is effectively shielded by the high sound insulation partition wall, and the quietness inside the vehicle compartment is improved. It works strongly to reinforce the shock absorber bracket, and the strength of the upper surface of the rear shock absorber bracket against the road thrust force is greatly improved.At the same time as improving the quietness of the passenger compartment, the rear shock absorber bracket that was conventionally used is This has the advantage of eliminating the need for reinforcement treatment.
