Description

The present invention relates to a vehicle seat cushion body and a vehicle seat. More specifically, when arranging a harness in a long groove provided on the surface of a flexible pad of a vehicle seat, the position of the long groove can be easily visually recognized. The present invention relates to a vehicle seat cushion body and a vehicle seat capable of stably holding the harness in the long groove while the method of assembling the harness into the long groove is simple.

Conventionally, in a seat cushion constituting a vehicle seat cushion body of a vehicle seat, a harness interposed between an electrical component or the like and a switch or the like has been routed.
For example, Patent Document 1 discloses a point in which a notch is provided in a pad and a harness is assembled therein with respect to such a harness arrangement.
More specifically, it is a seat cushion of a vehicle seat having a pad made of foam and a pan-shaped frame that supports the pad, and the pad is provided between an electrical component or the like and a switch or the like. It forms a notch to push in and assemble the harness to be assembled.

With such a configuration, the harness can be pushed into the notch formed in the pad and assembled, and the band and clip for fixing the harness can be eliminated, which reduces the cost of the harness and simplifies the handling of the harness. Can be achieved. Moreover, the harness can be routed only by connecting the electrical components and the connector to the connector. Further, in this case, since the harness is embedded in the continuously formed notches, the routing length of the harness can be shortened.
However, the type in which a notch is provided in such a pad has the following technical problems.

First, the harness assembly workability is poor. More specifically, when the pad is simply provided with a notch, the visibility of the notch position is poor, the work efficiency is low, and in order to improve the visibility of the notch position, the notch is a long groove having a simple U-shaped cross section. If the diameter of the harness is small, the harness may fall out of the groove and the assembling property is deteriorated.

Second, the stability and retention of the harness is poor. In order to ensure stable retention, a certain depth of cut is required, which adversely affects the processing cost of the pad and the workability of assembling the harness.

Hereinafter, the vehicle seat according to the embodiment of the present invention will be described with reference to FIGS. 1 to 6 by taking up the seat back 110 of an automobile as a specific example of the vehicle seat cushion body to which the harness H is arranged. ..
As shown in FIG. 1, the vehicle seat 10 of the present embodiment is for the driver's seat or the passenger seat, and the seat cushion 100 on which the occupant sits and the lower end portion can be rotated to the rear end portion of the seat cushion 100. It is provided with a seat back 110 connected to. The seat cushion 100 is connected to the vehicle body floor (not shown) by a slide mechanism (not shown), whereby the seat cushion 100 and the seat back 110 can be slid in the front-rear direction of the seat by the slide mechanism. .. Inside the seat cushion 100, a seat cushion frame (not shown) constituting the skeleton of the seat cushion 100 is provided. A seat cushion pad 120 made of a foam material such as urethane is provided on the upper side of the seat of the seat cushion frame, and the seat cushion pad 120 is covered with a cloth or leather seat cushion skin 130.

At the rear end of the seat cushion 100, a seat back 110 that supports the back of the occupant is arranged in an upright state. A seat back frame 160 constituting the skeleton of the seat back 110 is provided in the seat back 110, and the lower end portion of the seat back frame 160 is connected to the seat cushion frame via a conventionally known reclining mechanism 170. A seat back pad 140 made of a foam material such as urethane is provided on the front side of the seat of the seat back frame 160, and the seat back pad 140 is covered with a cloth or leather seat back skin 150. A headrest 190 is attached to the upper end of the seat back 110.

The seat back pad 140 is exemplified by a flexible pad made of polyurethane, for example. Known raw materials for polyurethane can be applied without limitation, and in order to exert the function as a cushion pad, it is selected in consideration of elasticity and the like, whereby the harness H is used as a seat back pad, as will be described later. When assembling to the long groove 16 formed on the surface of the 140, the seat back pad 140 can be deformed to widen the width of the groove opening 20 of the long groove 16. Further, the material may be selected from the viewpoint that the cushion pad has good moldability and does not cause a problem such as being caught when the cushion pad is released from the mold.

The seat cushion 100 has side frames 180 on both the left and right sides, and the seat back frame 160 in the seat back 110 is supported by the rear end of the side frame 180 so as to be reclining via the reclining mechanism 170.
According to the vehicle seat 10 having the above configuration, the occupant sits on the seat cushion 100 while facing forward (F direction in FIG. 1), and sits on the seat back 110 with his / her upper body resting from his / her back. ing.

As shown in FIG. 2, a harness H is arranged on the back surface of the vehicle seat 10. More specifically, the harness H is disposed on the back surface of the seat back 110 downward toward the vehicle floor. The harness H is a wire wire in which a plurality of electric wires are put together, covered with a corrugated tube, and a coupler is attached to an end portion, and power is supplied to electrical components such as a vibration motor M.

More specifically, as shown in FIG. 2, a vibration motor M for preventing the driver from falling asleep is installed at a predetermined position on the back side of the seat back pad 140, and the vibration generated by the vibration motor M is transmitted to the driver. This makes it possible to prevent the driver from falling asleep while driving. The vibration motor M is conventionally known and is connected to a power source (for example, a battery) via a harness H described later, although detailed description thereof will be omitted. Since the wire-shaped harness H itself connected to the vibration motor M also vibrates due to the vibration of the vibration motor M, as will be described in detail later, from the viewpoint of preventing resonance of the seat back frame 160 and preventing the generation of abnormal noise. Like the vibration motor M, the harness H is assembled in the long groove 16 of the seat back pad 140 without being directly fixed to the metal seat frame.

As shown in FIGS. 2 to 4, a long groove 16 into which the harness H is arranged is formed on the surface 14 of the seat back pad 140.
A harness holding portion 18 is formed in the long groove 16 at least in a part thereof, and the cross section of the harness holding portion 18 intersecting the extending direction of the long groove 16 becomes narrower toward the surface 14 of the seat back pad 140. The groove opening 20 formed on the surface 14 of the seat back pad 140 is configured to have the minimum width.

The long groove 16 continuously extends downward from the vibration motor M to the edge 28 of the seat back pad 140 on the back surface of the seat back pad 140, and the harness holding portion 18 is provided with a predetermined distance d from each other in the extending direction of the long groove 16. , Multiple installations. As a modification, the long groove 16 may extend so as to cross from one edge of the seat back pad 140 to the other edge.
The predetermined interval d may be determined from the viewpoint of stably holding the harness H in the long groove 16. For example, the portion of the elongated groove 16 having a small curvature is arranged with a narrow interval, and the portion having a large curvature or a straight portion has a predetermined interval d. , May be arranged with a wider interval.
As shown in FIG. 3 (A), the harness holding portion 18 and the long groove 16 may be provided so as to face each other at both edges of the harness holding portion 18 and the long groove 16, and as shown in FIG. 3 (B), the harness holding portion 18 is provided with the long groove. At both edges of 16, the elongated grooves 16 may be provided alternately in the extending direction.

The cross-sectional shape is a substantially U-shape that tapers toward the groove opening 20, and the groove bottom 26 is formed along a part of the outer circumference of the harness H.
The portion of the harness holding portion 18 that constitutes at least one of the facing side surfaces 22 of the long groove 16 constitutes an overhanging portion 24 that approaches the other facing side surface 22 toward the groove opening 20, thereby groove the harness H. The harness H is held in the long groove 16 by pushing it into the long groove 16 through the opening 20.

The length of the elongated groove 16 of the harness holding portion 18 in the extending direction and / or the width W of the groove opening 20 and / or the groove depth L of the elongated groove 16 are set according to the diameter D of the harness H.
In particular, the groove depth L is not more than twice the diameter D of the harness H.
For example, the diameter of the harness H including the exterior material is φ7.0 mm to φ10.0 mm, the width of the groove opening 20 is 2 mm, and the groove depth L is 15 mm.

The method for manufacturing a seat back pad of the present invention includes at least the following steps.
After injecting a foaming raw material (for example, a polyurethane foam stock solution composition) into a mold, foaming and curing, the mold set is released, and the molded product (seat back pad 140) is taken out from the mold, and the obtained seat back is obtained. The vibration motor M is positioned and temporarily fixed on the surface of the pad 140, and the harness H is assembled in the elongated groove 16.

In particular, when molding the seat back pad, the so-called waste resin 200 may be used to mold the harness holding portion 18. More specifically, since the cross section of the harness holding portion 18 intersecting the extending direction of the long groove 16 is narrow toward the groove opening 20, if the harness holding portion 18 is molded using only the mold, the die is removed. At this time, the overhanging portion 24 of the harness holding portion 18 may be torn off and remain on the mold side. Therefore, the waste resin 200 is used to ensure workability at the time of demolding.

As shown in FIG. 6, the waste resin 200 has a molded portion 210 molded into a shape complementary to the harness holding portion 18, and a magnet (not shown) is provided on the back surface 220 so that the waste resin 200 can be brought into close contact with the mold. The waste resin 200 is attached to the mold with a magnet to foam urethane, which is a pad material. After urethane foaming, the waste resin 200 is removed from the mold, and then the molded pad is removed from the mold. It is possible to eliminate the possibility that the overhanging portion 24 of the harness holding portion 18 is torn off and remains on the mold side as described above, and the discarded resin 200 may be discarded after being removed from the mold.
By using such a waste resin 200, even when the cross section of the harness holding portion 18 intersecting in the extending direction of the elongated groove 16 has a high degree of narrowing toward the groove opening 20, the above-described technique It is possible to avoid the problem.

According to the vehicle seat 10 having the above configuration, when the harness H is arranged in the long groove 16 provided on the surface 14 of the seat back pad 140 of the vehicle seat 10, the harness H is linearly arranged on the surface 14 of the seat back pad 140. The position of the long groove 16 can be visually recognized by the extending groove opening 20 (FIG. 4A), and the cross section of the harness holding portion 18 intersecting the extending direction of the long groove 16 is the surface 14 of the seat back pad 140. Since the width is narrowed toward the side and the groove opening 20 is configured to have the minimum width, the portion of the harness holding portion 18 that constitutes at least one of the facing side surfaces 22 of the long groove 16 is the groove opening 20. By forming an overhanging portion 24 that approaches the other facing side surface 22 toward the direction of the harness H, thereby pushing the harness H into the long groove 16 through the groove opening portion 20, the harness H is moved by the overhanging portion 24 into the groove opening portion 20. When the harness H is arranged in the long groove 16 provided on the surface 14 of the seat back pad 140 of the vehicle seat 10, the position of the long groove 16 can be easily visually recognized. At the same time, the harness H can be stably held in the long groove 16 while the method of assembling the harness H into the long groove 16 is simple.

In particular, in the case of a large-diameter harness H in which multiple wires are bundled, the seat back pad 140 is deformed to widen the groove opening 20 and the harness H is accommodated in the long groove 16 (FIG. 4 (B)). Since the overhanging portion 24 is not caught in the groove bottom portion 26 and the overhanging portion 24 is maintained as it is, the harness H is applied to the groove bottom portion 26 of the long groove 16 and above the harness H. Since the overhanging portion 24 overhangs, the overhanging portion 24 prevents the harness H from coming off from the long groove 16 and can be stably held in the long groove 16 (FIG. 4 (C)).

The second embodiment of the present invention will be described below with reference to FIG. In the following description, the same components as those in the first embodiment will be omitted by assigning similar reference numbers, and the feature portions of the present embodiment will be described in detail below.
The feature of the second embodiment of the present invention lies in the harness holding portion 18. In the first embodiment, when the harness H is assembled into the long groove 16, the overhanging portion 24 formed by the harness holding portion 18 is the harness H. In this embodiment, the overhanging portion 24 sandwiches and supports the harness H in the long groove 16 to support the harness H in the long groove 16, while the function of preventing the harness H from coming off from the groove opening 20 is achieved. The point is to keep it stable.

More specifically, the cross-sectional shape of the long groove 16 is determined according to the frictional force generated between the surface 14 of the seat back pad 140 and the outer peripheral surface of the harness H when the harness H is pushed into the long groove 16.
More specifically, the frictional force acting on the harness H is affected by the friction coefficient determined by the material of the skin material surrounding the harness H and the pinching force of the harness H by the overhanging portion 24. The cross-sectional shape of the long groove 16 may be determined from the viewpoint of stably holding the harness H in the long groove 16 in consideration of factors. For example, when the friction coefficient is high, the degree of overhang of the overhanging portion 24 may be determined. When the friction coefficient is low, the degree of overhang of the overhanging portion 24 may be increased.

The overhanging portion 24 is set to have a difference between the width W of the groove opening 20 and the maximum width Wmax of the elongated groove 16 so that the overhanging portion 24 can be pulled into the groove bottom portion 26 of the elongated groove 16 and deformed. When pushed into the long groove 16 through 20, the harness H is sandwiched and supported by the overhanging portion 24 in the long groove 16.

According to the vehicle seat 10 having the above configuration, when the harness H is arranged in the long groove 16 provided on the surface 14 of the seat back pad 140 of the vehicle seat 10, the harness H is linearly arranged on the surface 14 of the seat back pad 140. The position of the long groove 16 can be visually recognized by the extending groove opening 20 (FIG. 5A), and the cross section of the harness holding portion 18 intersecting the extending direction of the long groove 16 is the surface 14 of the seat back pad 140. Since the width is narrowed toward the side and the groove opening 20 is configured to be the minimum width, the portions of the seat back pad 140 that form the facing side surfaces 22 of the long groove 16 are pulled into the groove bottom 26 and deformed. A possible overhanging portion 24 is configured (FIG. 5B), and the overhanging portion 24 has the width of the groove opening 22 and the maximum width Wmax of the long groove 16 so that the overhanging portion 24 can be pulled into the groove bottom portion 26 of the long groove 16 and deformed. When the harness H is pushed into the long groove 16 through the groove opening 20, the surface portion of the seat back pad 140 near the edge 28 of the groove opening 20 becomes the harness H of the seat back pad 140. Even if the width of the groove opening 20 is expanded by simply pushing the harness H into the long groove 16, the harness H does not have to deepen the groove depth L of the long groove 16. When the harness H is arranged in the long groove 16 provided on the surface 14 of the seat back pad 140 of the vehicle seat 10 which is sandwiched and supported by the double overhanging portions 24 in the long groove 16 (FIG. 5 (C)), the long groove 16 The position is easily visible, and the harness H can be stably held in the long groove 16 while the method of assembling the harness H into the long groove 16 is simple.
