DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
One embodiment of the present invention will now be described with reference to the accompanying drawings. FIG. 1 shows a cable wiring construction in accordance with the embodiment, showing an example in which the cable wiring construction is applied to a seat 1 of a driver seat in a vehicle.
The seat 1 is fixed to a floor 12 via a unit body 11, and the unit body 11 is provided with a rotation mechanism 13 for turning the seat 1 by electrical power and a slide mechanism 14 for sliding the seat 1 forward and backward by electrical power. From the back surface on the vehicle rear R side of the unit body 11, a curl cord 15, which is a cable, extends, and at a tip end of the curl cord 15, a controller 16 is provided. This allows a seater on the seat 1 to take the controller 16 in his/her hand and operate buttons 17, . . . on the controller 16, and thereby the seat 1 can be turned or slid.
On a back surface 22 of a seat back 21 forming a backrest of the seat 1, a backboard 24 is detachably fixed with a plurality of clips 23, . . . as shown in FIG. 2. Between the backboard 24 and the seat back 21, a long locking member 25 is disposed.
As shown in FIG. 3, the locking member 25 is formed into a string shape, and in both end portions thereof, an upper loop portion 31 and a lower loop portion 32, which serve as locked portions, each consisting of an end portion tied in a loop shape are formed. Both the loop portions 31 and 32 are formed so as to have a size capable of inserting the clip 23 therethrough. As shown in FIG. 2, the loop portions 31 and 32 are fixed to the seat back 21 together with the backboard 24 in a state in which the upper and lower clips 23, 23 that fix the backboard 24 to the seat back 21 are inserted therethrough.
As shown in FIG. 3, in an intermediate portion of both the loop portions 31 and 32, a locking portion 41 formed by being tied to the curl cord 15 is provided so that a length 43 from the locking portion 41 to the lower loop portion 32 locked to the lower clip 23 is longer than a length 42 from the locking portion 41 to the upper loop portion 31 locked to the upper clip 23. Thereby, as shown in FIG. 2, the locking portion 41 is located at an upper position of the seat back 21 in a state in which the upper and lower loop portions 31 and 32 are locked to the upper and lower clips 23, 23.
The locking portion 41 is positioned in a state in which proximal end portions thereof are held between the seat back 21 and the backboard 24, and in such a state the length of the locking member 25 is set so that the locking portion 41 exits in an elongated form on the outer periphery of the backboard 24. Thereby, the locking portion 41 for locking an intermediate portion of the curl cord 15 is provided on the back surface 22 of the seat back 21 as shown in FIG. 2, and the height position of the curl cord 15 at a position of being locked in the locking portion 41 is set so as to be higher than a seat cushion 51 of the seat 1 as shown in FIG. 1.
At the side of the seat cushion 51 of the seat 1, a holder 52 for detachably holding the controller 16 is provided. Between the controller 16 held by the holder 52 and the locking portion 41, a droop prevention region 61 is provided to prevent the curl cord 15 from drooping downward from the seat cushion 51. Also, between the locking portion 41 and the unit body 11, an expansion contraction region 62 that is provided with an allowance for allowing the curl cord 15 to expand and contract at the seat sliding is provided.
In this embodiment configured as described above, the intermediate portion of the curl cord 15 extending from the unit body 11 to the controller 16 is locked to the locking portion 41 provided on the seat back 21, and the height position of the curl cord 15 in the locking portion 41 is set so as to be higher than the seat cushion 51.
Therefore, the height position of the curl cord 15 positioned between the controller 16 operated by the seater on the seat cushion 51 and the locking portion 41 can be kept higher than the seat cushion 51. Thereby, the curl cord 15 can be prevented from drooping downward from the seat 1.
Accordingly, the embodiment can prevent a trouble such as breaking of the curl cord 15 caused by pinching, as compared with the conventional cable wiring construction in which the curl cord 15 may droop downward from the seat 1 and may be caught by the rotation mechanism 13 or the sliding mechanism 14 of the unit body 11 provided under the seat 1. This prevents a trouble such that the controller 16 cannot be operated from happening.
Since the allowance of the curl cord 15 is provided in an expansion contraction region 62 between the locking portion 41 and the unit body 11, a load such as tension applied to the curl cord 15 according to the operation of the seat 1 can be prevented.
Also, the locking member 25 provided between the seat back 21 and the backboard 24 of the seat 1 can be positioned and fixed at three positions of clips 23, 23 at different locations and a held portion between the seat back 21 and the backboard 24.
Thereby, the locking portion 41 for the curl cord 15 can be provided without performing post-working such as forming a locking hole for locking the curl cord 15 in the seat back 21, or fixing a bracket therein, so that the original state can be restored.
In this embodiment, the locking portion 41 that is formed by tying the intermediate portion of the locking member 25 to the curl cord 15 has been explained as an example. However, the present invention is not limited to this configuration. For example, the locking portion 41 maybe formed by extending a part of folded portion of the locking member 25 from the backboard 24, or the locking portion 41 may be formed by providing a clip engaging detachably with the curl cord 15 in an intermediate portion of the locking member 25.
As described above, in the cable wiring construction in accordance with the present invention by locking the intermediate portion of the cable extending from the unit body to the controller to the locking portion provided on the seat back, the height position of the cable located between the controller operated by the seater on the seat cushion and the locking portion can be kept higher than the seat cushion. Thereby, the cable can be prevented from drooping downward from the seat.
The embodiment can therefore prevent a trouble such as breaking of a cable caused by pinching, as compared with the conventional cable wiring construction in which the cable may droop downward from the seat and may be caught by the sliding mechanism, the rotation mechanism or the like under the seat.
By providing the allowance of the cable between the locking portion and the unit body, a load such as tension applied to the cable according to the operation of the seat can be prevented.
Also, in the cable wiring construction in accordance with the present invention, the locking, member provided between the seat back and the backboard can be positioned and fixed at three positions of clips at different locations and a held portion between the seat back and the backboard.
Thereby, the locking portion for the cable can be provided without performing post-working such as forming a locking hole in the seat back or fixing a bracket therein, so that the original state can be restored.
