Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side hinge system of a folding sheet, more particularly, to absorbing an external force when an external force acts from the rear to the front of the folding sheet, Or a side hinge system of a folding sheet capable of suppressing the occurrence of rupture.
Vehicle fuel economy has been considered as a very important criterion for vehicle buyers to select vehicles for purchase, and weight saving of vehicles has become a key issue in vehicle development.
The prioritized measures to reduce the fuel consumption of the vehicle are to reduce the weight of the vehicle, thereby reducing the weight of the seat applied to the vehicle.
In order to reduce the weight of the vehicle seat, the material constituting the seat is replaced by plastic. In particular, the back panel of the seat, which is heavy in the seat, is replaced with a plastic material.
On the other hand, in order to maximize the utilization of the vehicle space, it is a tendency to design a folding seat of a vehicle. The advantage of folding is that it can be used as seat or trunk space depending on the presence of passengers.
However, as described above, when the weight of the back panel of the folding sheet changes from steel to plastic, weight is applied to the back of the sheet, cracks or breakage may occur in the back panel.
In the case of a back panel made of a steel material as in the prior art, since the material itself has a ductility property, it can absorb a certain amount of impact as it is deformed. On the other hand, plastic materials have brittle properties, Cracks will occur or breakage will occur.
Accordingly, in the case of a folding sheet of a vehicle, it is required to develop a technique that can achieve weight reduction by applying a plastic material and maintain the strength at substantially the same level as that of a conventional steel material.
It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a folding seat which is capable of securing the safety of a passenger by absorbing an external force when an external force acts on the folding sheet from the rear to the front, Thereby providing a hinge system.
According to an aspect of the present invention,
A hinge pin projectingly fixed to the back panel side portion of the folding sheet;
A side bracket fixed to the lateral body of the folding sheet and having a sliding groove that is engaged with the hinge pin so as to be movable back and forth; And
Wherein the hinge pin is fixed to the first region of the sliding groove when an external force smaller than a predetermined reference value is applied to the folding sheet, An elastic fixing means for causing the elastic fixing means to be transferred to the region;
The side hinge system of the folding sheet according to the present invention includes:
In one embodiment of the present invention, the sliding groove may be formed such that the hinge pin is movable in the front-rear direction of the vehicle.
In one embodiment of the present invention, the side bracket may have a convex portion fixed to be in contact with the vehicle body of the vehicle and a recess formed with the sliding groove.
In one embodiment of the present invention, the hinge pin includes a latching jaw which is disposed in the recess of the
In one embodiment of the present invention, the first area is an area close to the rear of the vehicle in the sliding groove, and the second area may be an area near the front of the vehicle in the sliding groove.
In one embodiment of the present invention, the elastic fixing means is a wire having an annular shape opened in one direction, and a portion of the wire extending in the open direction is spaced apart from the first region to the second region And the remaining portion except for the part may have a shape surrounding the second region.
In one embodiment of the present invention, the wire may be fixed at a portion of the portion surrounding the second region, the portion corresponding to the foremost portion of the vehicle adjacent to one end of the sliding groove.
According to another aspect of the present invention,
A hinge pin projectingly fixed to the back panel side portion of the folding sheet;
A side bracket fixed to the lateral body of the folding sheet and having a sliding groove that is engaged with the hinge pin so as to be movable back and forth; And
Wherein the hinge pin is fixed to a first region of the sliding groove near the rear of the vehicle when an external force smaller than a predetermined reference value is applied to the folding sheet, And elastically securing means for causing the gas to be transported along a groove to a second region close to the front of the vehicle,
Wherein the elastic fixing means is a wire having an annular shape opened in one direction and a portion of the wire extending in the open direction has a structure in which the distance from the first region to the second region is narrowed, And a portion of the portion surrounding the second region corresponding to the foremost portion of the vehicle is fixed to a portion adjacent to one end of the sliding groove. Side hinge system.
According to the side hinge system of the folding seat, when the external force acting on the vehicle front side on the back panel side of the folding sheet is equal to or larger than a certain size, the hinge pin itself is transferred to the front of the vehicle, The impact can be absorbed.
Accordingly, safety of the passenger can be secured by absorbing impact transmitted to the occupant seated on the seat through the side hinge system of the folding seat. In addition, even when the back panel of the folding sheet is made of plastic having no ductility, generation of cracks or breakage in the back panel is suppressed.
Further, according to the side hinge system of the folding sheet, when the hinge pin is fixed and an external force equal to or greater than a specific size is applied, a wire processed into a specific shape is employed as the elastic fixing means for allowing the hinge pin to be transported along the sliding groove , No separate bracket machining is required, and the reference value of the external force to which the hinge pin can be transferred can be set freely, which increases the degree of freedom of design.

Hereinafter, a side hinge system of a folding sheet according to various embodiments of the present invention will be described with reference to the accompanying drawings.
1 is a front view showing an example of a folding sheet to which a side hinge system of a folding sheet according to an embodiment of the present invention is applied.
As shown in Fig. 1, in order to utilize the space of the vehicle, the upright seat of a vehicle is designed as a foldable foldable seat. The folding sheet is folded forward by the hinge system so that it can be utilized as a trunk space with the back panel of the sheet as the bottom.
Back panels of folding sheets have been made of steel, but most of them have been replaced by plastic materials in order to save weight of vehicles. The back panel of the steel material has ductility due to the characteristics of the steel material, so that it can absorb the impact while being deformed when an external force acts on the back. However, the back panel of the plastic material has brittleness as a material characteristic. But a crack is generated or a fracture occurs.
Therefore, the back panel of the folding sheet, in particular the back panel of the folding sheet employing the plastic material, can suppress cracks and breakage caused by external force, and furthermore assures the safety of the occupant seated on the seat through shock absorption A technique that can be applied should be applied.
In the present invention, when a hinge system of a folding sheet is used to absorb an external force when an external force acts from the rear to the front, it is possible to secure the safety of the occupant seated on the seat and to suppress cracking or breakage of the back panel of the folding seat Technology.
