Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a seat hinge for attaching an automobile seat cushion to a floor panel in a freely undulating manner.

Prior Art In order to mount an automobile seat cushion to a floor panel in a freely undulating manner, for example,
Japanese Patent No. 192837 discloses a seat hinge configuration shown in FIG. In the figure, 1 is a seat cushion, 2 is a floor panel, and a seat hinge 3 is interposed between both 1 and 2.
can be freely raised and lowered in the direction of arrow A. As shown in FIG. 4, the seat hinge 3 includes a seat bracket 4 fixed to the lower surface of the seat cushion 1;
Floor bracket 5 fixed to floor panel 2
The seat bracket 4 is mainly composed of a pivot pin 6 that rotatably pivots both the brackets 4 and 5.
Mounting holes 7, 7 and floor bracket 5 opened in
Fasteners (not shown) are inserted into mounting holes 8 opened in the front and fixed to the lower surface of the seat cushion 1 and one end surface of the floor panel 2, respectively.

Problems to be Solved by the Invention However, with such conventional vehicle seat hinges, the dimensions of the seat hinge 3 cannot be made sufficiently large due to constraints such as the space and weight of the seat mounting portion. , the floor bracket 5 of the seat hinge 3 is attached to the floor panel 2.
When the carpet is fixed to the floor panel 2, the pile of carpet laid on the floor panel 2 cannot be held down, and the end of the pile gets caught between the pivot pin 6, the seat bracket 4, and the floor bracket 5, resulting in the notch in the pile end. Also, there were problems such as the pile falling out. Therefore, there is a problem in that damage to the carpet near the seat hinge 3 progresses over time, resulting in poor appearance.

Therefore, the present invention solves the problems that conventional vehicle seat hinges have, as described above, and prevents the carpet pile end from being pinched and notched during use, and the pile from falling out. This invention provides a vehicle seat hinge.

Means for Solving the Problem: A pivoting portion between the pivot pin and both brackets is protected from the carpet on the floor bracket near the pivot pin rotatably pivoting the seat bracket and the floor bracket. A shielding plate is provided protrudingly.

Function When the floor bracket is fixed to the floor panel, the shielding plate protruding from the floor bracket presses the carpet pile, so the end of the pile connects with the shaft attachment part of both brackets. The phenomenon of being caught between the pins is prevented by the shielding plate.

Embodiment The structure of a vehicle seat hinge according to the present invention will be described below based on the drawings.

That is, in the configuration shown in FIG. 1, the seat hinge 11 shown as a whole is connected to the seat cushion 1
a seat bracket 4 fixed to the lower surface of the floor panel 2; and a floor bracket 5 fixed to the floor panel 2.
The main body is a pivot pin 6 that pivotally connects both brackets 4 and 5, and the seat bracket 4
Mounting holes 7, 7 and floor bracket 5 opened in
Fasteners (not shown) are inserted into the mounting holes 8 opened in the front and fixed to the lower surface of the seat cushion 1 and one end of the floor panel 2, respectively.

On the outer surfaces 5a, 5a of the floor bracket 5 in the vicinity of the pivot pin 6, cut and raised pieces 12, 12 are formed by cutting out a part of the wall surface forming the floor bracket 5 in a substantially U-shape and bending it outward. is provided. The cut and raised pieces 12, 12 have the function of a shielding plate that protects the pivoting portions of the brackets 4, 5 and the pivot pin 6 from the pile of carpet laid on the floor. Note that the cut and raised pieces 12, 12 are an example of a shielding plate, and the present invention is not limited to the shape example of the cut and raised pieces 12, 12. For example, a separately formed shielding plate can be used outside the floor bracket 5. It may be fixed and protruded on the side surfaces 5a, 5a.

The vehicle seat hinge 11 according to the present invention having such a configuration is shown in FIG. 2, which is a cross section when the seat bracket 4 is fixed to the lower surface of the seat cushion 1 and the floor bracket 5 is fixed to the floor panel 2. Similarly, the cut and raised pieces 12,1 serve as shielding plates.
2 is carpet 1 installed on floor panel 2
It has the effect of holding down the pile 14 extending from 3,
Therefore, the effect of protecting the pivoting portion between the pivot pin 6 and the brackets 4 and 5 from the pile 14 of the carpet 13 is brought about. Therefore, seat cushion 1
Even when the pile 14 is moved up and down, the tip of the pile 14 is prevented from wrapping around the shaft attachment portion between the pivot pin 6 and both brackets 4 and 5.

Effects of the Invention The vehicle seat hinge according to the present invention described in detail above has an axis between the pivot pin and both brackets, which is attached to the floor bracket in the vicinity of the pivot pin that rotatably connects the seat bracket and the floor bracket. Since a shielding plate is provided to protect the floor bracket from the carpet, when the floor bracket is fixed to the floor panel, the shielding plate can press down on the pile of carpet laid on the floor, and the end of the pile can be placed at the pivot point. It is possible to prevent the support pin from being caught between the support pin and both brackets. Therefore, even when the seat cushion is raised and lowered, the pile of the carpet does not cut out or fall out, and the carpet is prevented from being damaged over time and the appearance can be maintained in good condition.
