Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a harness fixing structure for a vehicle.
[0002]
[Prior art]
Various harnesses are arranged on the back surface of interior panels such as headlinings, door trims, and luggage side trims of automobiles. For example, a harness for lighting and various electric components is fixed to a head lining attached to a lower side of a roof panel (for a similar technique, see JP-A-2000-108810).
[0003]
As a fixing structure of the harness to the head lining, a groove is formed on the back of the head lining along the wiring route of the harness, the harness is inserted in the groove, and several places from the top are fixed with adhesive tape I have. Then, the end of the harness is taken out from the edge or the middle of the head lining, and is connected to lighting and electrical components. The concave groove formed on the back surface of the head lining is formed at a depth within the range of the thickness of the head lining in order to prevent irregularities from appearing on the front surface side exposed inside the vehicle. Therefore, the head lining is formed thick to secure a sufficient depth for housing the harness.
[0004]
[Problems to be solved by the invention]
However, in such a conventional technique, the thickness of the head lining is increased in order to provide the concave groove for storing the harness, so that the weight of the head lining increases, which causes an increase in the weight of the vehicle body. Also, as the headlining becomes thicker, the cabin space is also squeezed and narrowed.
[0005]
Further, when the vehicle running vibration is applied, the harness may vibrate inside the concave groove to generate low-grade vibration sound. Such a problem is common not only to the headlining but also to other interior panels attached to the vehicle body from the vehicle interior side.
[0006]
The present invention has been made by paying attention to such a conventional technique, and provides a harness fixing structure that does not require the interior panel to be thick and that can reliably prevent harness vibration.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
[0020]
1 to 3 are views showing a first embodiment of the present invention. The head lining 1 is an interior panel attached to a lower side of a roof panel (not shown). The headlining 1 is formed with a thickness sufficient to obtain rigidity necessary for forming a ceiling in a vehicle cabin. An opening 2 for a room lamp is formed in front of the headlining 1.
[0021]
A plurality of branched harnesses 3 are fixed to a portion of the back surface of the head lining 1 behind the opening 2. The harness 3 is used to supply power and signals to electrical components around the roof, and each of the branched ends is provided with a connector 4 for connection.
[0022]
The routing route of the harness 3 is defined by being held between the pair of seats 5 and 6. The sheets 5 and 6 are both flexible, and are formed of, for example, felt, nonwoven fabric, urethane, polyester, cotton, cloth, nylon, or the like. The sheets 5 and 6 are adhered to each other with an adhesive or a double-sided adhesive tape.
[0023]
The harness unit 7 is formed by bonding the pair of sheets 5 and 6 with the harness 3 interposed therebetween. From the harness unit 7, a plurality of ends having the connector 4 are taken out for connection with electrical components. In particular, the upper sheet 5 is formed with a notch 8 and an opening 9 that accurately define the position of the takeout portion of the harness 3.
[0024]
The harness unit 7 is prepared in advance, and the harness unit 7 is bonded to the back surface of the head lining 1 with an adhesive or a double-sided adhesive tape, so that the harness 3 is bonded and fixed to the back surface of the head lining 1. Can be. Since the harness 3 can be fixed along the predetermined route only by bonding the harness unit 7, the fixing work of the harness 3 is also easy.
[0025]
Since the harness 3 thus adhered and fixed is sandwiched between the pair of seats 5 and 6, the harness 3 does not vibrate even when vehicle running vibration is applied. No sound is produced. Also, in order to fix the harness 3, it is not necessary to change the shape of the head lining 1 and it is not necessary to make the head lining 1 particularly thick, so that the weight of the head lining 1 is light, contributing to the weight reduction of the vehicle body. be able to.
[0026]
4 and 5 are views showing a second embodiment of the present invention. In the second embodiment, a pair of sheets 10 and 11 bonded to each other are formed by bending one sheet. Openings 13 for taking out a part of the harness 3 are formed in the bent portions 12 of the sheets 10 and 11. Further, a slit 14 is formed near the front edge of the harness 3. The harness 3 becomes the harness unit 15 held between the pair of sheets 10 and 11 adhered to each other as in the previous embodiment.
[0027]
In the second embodiment, since the pair of sheets 10 and 11 is formed by one sheet, the alignment when bonding the pair of sheets 10 and 11 is accurate, and the bonding near the bent portion 12 can be omitted. Therefore, the bonding operation is easy. Then, the created harness unit 15 is bonded to the back surface of the head lining.
[0028]
When the harness 3 of the part taken out from the sheets 10 and 11 becomes long when the pair of sheets 10 and 11 are bonded, the take-out length is adjusted by pushing the sheet into the pair of sheets 10 and 11 and bonding. If it is possible to increase the length of the harness 3, it is possible to shorten the length of the harness 3 by forming the harness unit 15 and then taking out the long harness 3 through the slit 14 again. can do.
[0029]
FIG. 6 is a diagram showing a third embodiment of the present invention. In the third embodiment, of the pair of sheets 16 and 17, the lower side is a flexible sheet 17 as in the previous embodiment, but the upper side is a rigid resin sheet 16. Then, a clip seat 18 as a “fixed structure” to an unillustrated roof panel was formed on the upper rigid sheet 16.
[0030]
After the harness unit 19 is adhered to the back surface of the head lining, the clip seat 18 is fixed to the upper roof panel with a clip, so that the head lining is fixed to the roof panel via the harness unit 19. . Since the clip seat 18 is formed on the rigid seat 16, the fixing is reliable.
[0031]
FIG. 7 is a diagram showing a fourth embodiment of the present invention. In the fourth embodiment, contrary to the third embodiment, the lower side is a rigid sheet 16 and the upper side is a flexible sheet 17. Then, a clip seat 18 was formed on the rigid sheet 16, and an opening 20 for exposing the clip seat 18 was formed on the flexible sheet 17.
[0032]
Therefore, after the harness unit 21 formed by bonding the sheets 16 and 17 to each other is bonded to the back surface of the head lining, the clip seat 18 exposed from the opening 20 is fixed to the roof panel with a clip, so that As in the third embodiment, the headlining can be indirectly fixed to the roof panel.
[0033]
In particular, in the fourth embodiment, since the flexible sheet 17 can be sandwiched between the rigid sheet 16 fixed to the roof panel and the roof panel, even if a downward force is applied from the headlining, the force is reduced. Since the rigid sheet 16 is directly transmitted to the roof panel via the clip seat 18 and is not applied to the flexible sheet 17, no force in the peeling direction acts between the rigid sheet 16 and the flexible sheet 17. Therefore, the force for fixing the head lining is strong.
[0034]
In each of the embodiments described above, the headlining is used as an example of the interior panel. However, the present invention is not limited to this, and the present invention can be applied to other interior panels in which the harness is fixed to the back surface.
