[Field of design]

The present invention relates to a reinforcing structure of a center pillar of an automobile, and more particularly, by moving a seat belt locking retractor to a lower side of a seat, thereby arranging a reinforcing member in an inner space of a center pillar formed by The present invention relates to a reinforcing structure of a center pillar of an automobile, in which rigidity is increased to reinforce stiffness against side collisions.

[Private Technology]

In the automobile, the seat belt 101 for the occupant of the front seat 100 is disposed in the center pillar disposed between the front and rear doors to support the roof and to which the rear door is mounted, as shown in FIG.

The seat belt 101 is fixed to the one end of the seat 100, the front end of the belt 104, which is drawn out from the locking retractor 103 disposed below the center pillar 102, as known in the On the 104, an anchor 105 free to move is disposed.

And the other side of the seat 100 by arranging the buckle 106 to which the anchor 105 can be coupled to couple the anchor to the buckle 106, the belt 104 to the upper body including the waist of the occupant It is possible to depress.

As described above, in installing the locking retractor 103 inside the center pillar 102, the hole 108 is drilled in the inner panel 107 as shown in FIG. The locking retractor 103 was provided through this, and as a reinforcement structure, both flange portions of the multi-shaped reinforcement panel 109 were fixed around the hole 108 of the inner panel 107.

However, in the case of arranging the locking retractor as described above, a hole is drilled in the center pillar inner panel, and the locking retractor occupies a considerable amount of space, thereby reducing the rigidity of the center pillar.

Accordingly, there is a problem that it is easily deformed even in the small side impact, and the damage of the vehicle body is increased and the safety of the occupant cannot be secured.

[Intention summary]

Therefore, the present invention has been devised to solve the conventional problems as described above, the purpose of the present invention is to increase the rigidity of the center pillar to increase the rigidity for side collisions, so as to damage the vehicle body during side impacts and to ensure the safety of the occupants It is to provide a reinforcement structure of the center pillar of a car so that it can be secured.

In order to realize this, the present invention is a center pillar of an automobile body in which a locking retractor of a seat belt is disposed under the inner side and an outer panel, and the locking retractor is disposed below the seat, The belt passing through the inside of the pillar can be wound around the locking retractor through a guide installed on the lower floor of the center pillar, and a reinforcement member formed of an inner reinforcement panel and an out reinforcement panel is provided between the inner panel and the out panel of the center pillar. Provided is a center pillar reinforcement structure of an automobile formed by arrangement.

The reinforcing member is such that the inner reinforcement panel has the same shape as the center pillar inner panel so that both flanges are interposed between the center pillar and the joint of the outer panel, and the outer reinforcement panel is coupled to the outside of the inner reinforcement panel. The cross-section is formed in a multi-shape so that both flanges are fixed to the outer surface of the inner reinforcement panel, the bent portion between the two flanges fixed to the state in contact with the inner surface of the center pillar out panel Provide reinforcing structures.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention capable of realizing the above object in detail as follows.

EXAMPLE

1 is a perspective view of the inner surface of the center pillar for showing the application of the subject innovation, the seat belt 10 is disposed in the center pillar 1 is a locking retractor (arranged below the center pillar 1 as in the prior art) An end 13 of the belt 12 drawn out from 11 is fixed to one side of the seat 2, and an anchor 13 freely movable is disposed on the belt 12.

And the other side of the seat 2 by arranging the buckle 14 to which the anchor 13 can be coupled to couple the anchor to the buckle 14, the belt 12 is the upper body including the waist of the occupant It is possible to depress.

In the seat belt mounting structure, the present invention arranges the locking retractor 11 under the seat 2 and guides the belt 12 to pass on the lower floor 20 of the center pillar 1. 21) was installed.

The reinforcing member 3 is disposed between the inner panel 15 and the out panel 16 of the center pillar 1 in which the locking retractor 11 is removed.

The reinforcement member 3 is composed of an inner reinforcement panel 30 and an out reinforcement panel 31. The inner reinforcement panel 30 has the same shape as the center pillar inner panel 15 so that both flanges thereof are centered. The fixing is interposed between the filler inner and the joints of the outer panels 15 and 16.

In addition, the outer reinforcement panel 31 coupled to the outside of the inner reinforcement panel 30 is formed in a cross-sectional shape, both flange portions 310 and 311 are fixed to the outer surface of the inner reinforcement panel 30. The bent portion 312 between the flange portions 310 and 311 is fixed in contact with the inner surface of the center pillar out panel.

The fixing means of each panel in the above is by welding as known.

As such, when the reinforcing member 3 is disposed between the inner panel 30 and the out panel 31 of the center pillar, the center pillar 1 is formed in the form of a double box, and its rigidity is greatly increased.

Accordingly, it is not easily deformed by the impact during the side collision, thereby reducing the damage of the vehicle body is a useful design that can increase the safety of the occupants.

Claims (2)
