Definitions
- the present invention relates to vehicle seats and, more specifically, to the structure of the headrests provided on vehicle seats. Background art
- FIG. 1 is a perspective view showing a conventional headrest.
- the X-axis is set in a direction from the rear side of the headrest 100 to the front side.
- set the Y axis in the direction from the lower surface of the headrest 100 to the upper surface, and set the left side of the headrest 100 to the right side.
- the X, Y, and Z axes intersect each other at right angles.
- the seat cushion and the seat back that holds the seat cushion are not shown because they are known.
- the headrest 100 is composed of a stage 101 and a headrest body 102.
- the stage 101 is formed by bending a metal pipe in an inverted U-shape.
- Stay 101 is fixed to the top of the seat knock
- the main body 103 a and 103 b of the stay 101 (the vertical axis of the stay 101) are respectively placed on the pair of holders (not shown). By wearing it, it is vertically engaged with the sheet knock (see the official publication No. 7-36967).
- the headrest body 102 is composed of a bracket 106, a pad 108, and a skin 109.
- the bracket 106 is connected to a pair of bearings 107 a and 107 b provided on the side surface of the bracket 106.
- the connecting portion 104 of the stay 101 supports the rotation by itself. It is done.
- the pad 108 made of polyurethane foam is molded by urethane liquid foaming, and the connecting portion 104 of the stay 101 is formed.
- the bent portions 105a, 105b and bracket 106 are covered.
- the skin 109 made of cloth or the like covers the pad 108 to form the headrest body 102. With such a configuration, the headrest 100 is fixed to rotate automatically with respect to the seat knock.
- FIG. 2 is a cross-sectional view of the conventional headrest in the Y-Z plane of the headrest shown in FIG.
- the lower surface of the headrest body 102 facing the seat knock guides the stay 101 into the interior of the headrest body 102.
- recesses 110a and 110b are formed.
- the connecting portion 104 and the bent portions 105 a and 105 b of the stay 101 are housed inside the headrest body 102.
- a recess 2 is provided inside the headrest body 102 from the recesses 110a and 110b to accommodate the stay 101.
- the pad 108 is formed, one of the receiving ports is provided with a urethane liquid or a semi-solid pad existing inside the headrest body 102.
- Patches 11a and 11b are installed to prevent the leak from leaking out of the headrest body 102.
- the patches 11a and 11lb are fixed to the stay bodies 103a and 103b at the respective accommodation openings.
- FIGS. 3A and 3B are cross-sectional views of the conventional headrest shown in FIG. 2 taken along the line SE 1-SE 1.
- FIG. 4 is a perspective view of a conventional headrest, in which a portion C of the headrest shown in FIG. 1 is enlarged.
- the stay body 103 of the stay 101 is engaged with a pair of holders fixed to the top of the sheet pack in a vertically movable manner.
- the headrest body 102 is connected to the bracket 110 via the bearings 107a and 107b of the bracket 106.
- the headrest main body 102 is connected to the connecting part 104 of the head 101 because the headrest main body 102 is supported by the rotation of the connecting part 104 of the head 101. With the center as the center, it is rotatable in the direction of the arrow shown in FIG.
- the patch 1 11 a When rotating, the patch 1 11 a is fixed to the stay main body 103 a, so that the right side with respect to the center axis M 1 of the concave portion 110 a is There is a gap between the patch 1 11a and the recess 1 10a. Therefore, there is a possibility that urethane liquid or semi-solid pad may leak out of the headrest body 102 from this gap. is there . The same can be said for the recess 110b.
- pad 108 will also form outside of headrest body 102 As a result, the appearance of the headrest 100 becomes ugly, and the pad 10 formed on the outside of the headrest main body 102 is formed. 8 has to be removed manually, which is time-consuming. Further, the gap between the patches 11 la and 11 b and the recesses 110 a and 110 b is filled with the node 108 so that Dress G The main body 102 does not rotate smoothly.
- the stay 101 is moved along with the headrest. Since the area of the storage port not covered with the skin 109 for storing inside the storage body 102 is increased, the pad 108 is formed. At this time, when the headrest body 102 rotates forward or backward due to the foaming pressure of the urethane liquid, the urethane liquid or semi-solid The possibility that the pad in the form of a body leaks out of the headrest body 102 is increased.
- the shape of the headrest body 102 may be reduced.
- the degree of freedom is limited.
- the present invention has been proposed in view of the above-described circumstances, and when forming a headless head, The possibility of leakage of urethane liquid or semi-solid pad from the storage opening for storing the stay inside the headrest is reduced. In addition, the gap between the lower surface of the headrest and the upper part of the stay is reduced to provide a headrest with a high degree of freedom for molding.

Is in close contact with Therefore, there is almost no possibility that the urethane liquid or the semi-solid pad leaks out of the headrest body 3.
- FIG. 8B when forming the pad 6, the headrest body 3 is turned forward by the foaming pressure of the urethane liquid.
- the accommodating port 10a is formed in the same axis position as the connecting part 5 of the 'stay 2', which is the rotation axis of the headrest body 3, so that The opening 10a is always in close contact with the connecting portion 5 of the stay 2 and laid. Therefore, there is almost no possibility that the urethane liquid or the semi-solid pad leaks out of the headrest body 3. The same can be said of the containment opening .10b.
- the receiving openings 10a and 10b are provided only on the side surfaces 12a and 12b of the concave portions 9a and 9b. Since it is formed, there is no need to install a patch in the storage port as in the conventional headrest. Further, since the storage ports 10a and 10b are brought into close contact with the connecting portion 5 of the stay 2, the urethane liquid is released when the pad 6 foams. Even if the headrest body 3 rotates forward or backward due to the bubble pressure, the leakage of the urethane liquid or the semi-solid node is ensured. It can be prevented.
- the skin 7 including the recesses 9a and 9b is made of a cloth material having elasticity, the relationship between the skin 7 and the stage 2 is made. Joint work is easy. Furthermore, since there is no need to install a notch as in the conventional case, each distance between the storage ports 10a and 10b and the connecting portion 5 of the stay 2 is not required. Can be reduced, and the freedom regarding the shaping of the headrest body 3 is not limited.
- the storage openings 10 a and 10 b are formed at the same axis position as the connecting portion 5 of the stay 2, which is the rotation axis of the headrest body 3. Therefore, even if the headrest main body 3 rotates forward and backward, the close contact between the storage openings 10a and 1Ob and the stay 12 will not be loosened.
- the accommodation opening for accommodating the connecting portion of the vehicle is a headless body. It is formed on the side surface of the recess formed on the lower surface of the headrest main body so as to be at the same axis position as the connecting part of the stay that becomes the rotation axis of the head rest body.
- the urethane liquid or semi-solid state Leakage of the head can be reliably prevented.
- the distance between the lower surface of the headrest body and the connection part of the stay is small.
- the freedom in shaping the headrest body does not need to be restricted.
- the diameter of the storage opening should be the same as the diameter of the connecting part of the stay.
