る。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tether anchor mounting structure for a child seat. 2. Description of the Related Art There are various types of child seat mounting structures . As shown in FIG. 5 , a tether 12 having a hook 13 attached to a tip thereof is fixed to an upper portion of the back of a backrest, and the back of the backrest. A child seat 11 having a connector 14 fixed to a lower anchor (not shown) is provided below. FIG To install such a child seat 11 to the seat
As shown in FIG. 6 , the hook 13 is fixed to the tether anchor 3 which is fixed to the reinforce 2 having a closed cross section extending in the left-right direction of the vehicle and joined to the interior side of the back panel 1 of the cab, as shown in FIG. Is hung. The tether anchor 3 is, as shown in FIG.
The structure is such that the collar 15 and the bolt 17 are fastened and fixed to the nut 15 fixed inside the upright surface of the reinforcement 2. Conventionally, a mounting piece 19 for maintaining strength is joined to the inside of the upright surface of the reinforce 2, but a front load load F is applied to the child seat 11.
When the tension occurs, the tensile force of the tether 12 acts on the reinforce 2, and before the load, the reinforce 2 is in a normal form as shown in FIG. 8A , but after the load, the purpose of the strength is achieved. However, as shown in FIG. 13 (b), the upright surface of the reinforce 2 may be pulled up to cause buckling deformation. [0005] In order to solve this problem, the material is changed by using a high-tensile steel plate of the Reinforce 2 and the size of the closed section is increased.
It is necessary to take measures such as increasing the thickness of the mounting piece 19 and adding a new reinforce. For this purpose, a large increase in cost, weight, and size of the reinforce, and the increase or increase of the reinforce, require space in the space occupied by the reinforce. This leads to a reduction in space, which is not desirable. SUMMARY OF THE INVENTION An object of the present invention is to provide a tether anchor mounting structure for securing a child seat, in which a simple structure is added to a conventional reinforce to secure the strength and rigidity of preventing reinforce deformation without increasing cost and weight. That is. SUMMARY OF THE INVENTION In order to achieve the above object, the gist of the present invention is to provide a vehicle having a closed panel having a closed section extending in the lateral direction of the vehicle and having a closed panel extending to the vehicle interior side. In a car having a tether anchor bracket for fixing a child seat to the reinforce,
Within the closed cross section of the reinforce, the reinforce
An elevation having an elevation in a direction perpendicular to the elevation of the
Parallel to the upper and lower surfaces of the reinforcement
Upper and lower parts are formed and separated at a predetermined interval
Between the pair of reinforcing members
Reinforced body connected by a connecting part parallel to the plane
The upper and lower surfaces of the reinforcing member are fixed to the upper and lower surfaces of the base
Then, the tether anchor bracket is
It is characterized in that it is fixed to the outside of the elevation of the reinforcement . Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a back panel,
Reference numeral 2 denotes a closed-section rain force which is joined to the back panel 1 in the vehicle interior and extends in the left-right direction of the vehicle. Reference numeral 3 denotes a tether anchor bracket for fixing a child seat, which is attached to the rain force 2. The present invention applies the rain force 2 from the tether 12 to the rain force 2.
And means for suppressing deformation of the reinforce 2 when a load is applied thereto . Hereinafter, embodiments of this specific means will be described. FIG . 2 is a sectional view corresponding to AA in FIG.
FIG. 8 is a perspective view of a main part of the present invention. As shown in FIG.
This is a structure in which a reinforcing member 5 is fixed in a closed cross section of the reinforce 2 in the vicinity of a mounting portion of the tether anchor bracket 3. The reinforcing member 5 has an upright portion 5a having an upright surface in a direction orthogonal to the upright surface of the reinforce 2, and an upper surface portion 5b and a lower surface portion 5c parallel to the upper and lower surfaces of the reinforce 2, and has a U-shaped cross section. There is a structure in which a pair of left and right reinforcing members 5 are connected to each other at predetermined intervals in a relative direction by a connecting portion 5d parallel to the rising surface of the reinforcement 2. This reinforcement 5
The upper surface 5b and the lower surface 5c of the reinforcing member are welded to the upper and lower surfaces of the reinforce 2, respectively, and the connecting portion 5d is welded to the upright surface of the reinforce 2. The tether anchor bracket 3 has an attachment structure welded 18 to the outside of the vertical surface of the reinforce 2 at the connection portion 5d. In the structure of the present invention , the reinforcement 5 is added to the conventional structure composed of the back panel 1 and the reinforcement 2, and the load from the tether 12 to the reinforcement 2 is not changed without changing other parts. The strength and rigidity for suppressing the deformation of the reinforcement 2 under load are improved, and the storage space is not reduced. In addition, since a large number of welding portions for fixing the reinforcing member 5 to the reinforcement 2 can be set above and below the reinforcement 2, more strength and strength can be obtained.
The rigidity is improved. As described above, the present invention does not significantly change the structure of the conventional back panel 1 and the reinforce 2, and the strength for suppressing the deformation of the reinforce 2 when a load is applied to the reinforce 2 from the tether 12. The rigidity is improved and the storage space is not reduced. At the same time, it is possible to secure the strength near the opening such as the back window. In the present invention having the above structure, the tether anchor bracket 3 is attached to the reinforcement 2 by welding 18 on the outer side of the upright surface, but it may be fixed by bolts and nuts. In addition,
By using a mounting structure in which the anchor anchor 3 is welded 18 to the outside of the elevation of the reinforcement 2, a bolt and nut for attaching the tether anchor bracket 3 are not required, and the number of parts and cost can be reduced. The number of the reinforcing members 5 is not limited to one, but may be plural if necessary. As described above, according to the present invention, the strength and rigidity of the reinforcement are reduced without increasing the weight and without increasing the weight of the conventional structure comprising the back panel and the reinforcement. This has the advantage that the deformation of the reinforce can be suppressed when a load is applied to the reinforce from the tether of the child seat without reducing the storage space.
