Description

  The present invention relates to a wire harness protector that accommodates and holds the wire harness, which is fixed on a vehicle-mounted member in which accessory positions to which the wire harness is connected are set in two ways.

  When wiring a wire harness connected to an auxiliary machine (such as an electrical component connector) installed in a vehicle seat (seat) or door to the seat or door, the wire harness is a substantially cylindrical wire harness protector. Various wiring harness wiring structures that are housed in the housing and fixed to structural members such as the seats and doors have been proposed (see, for example, Patent Document 1 below).

  By the way, for example, in the case of a vehicle seat, depending on whether it is arranged on either the left or right side of the vehicle, there are cases where the accessory position of the auxiliary machine is set in two ways opposite to each other. In this way, the wire harness routed on the vehicle-mounted member such as the seat in which the accessory equipment is set in two ways, depending on the fixing position of the wire harness protector, can be connected from the end portion on the outlet side of the protector. There will be a difference in the length of the routing route to the equipment position.

  Therefore, conventionally, one of the following two methods has been selected as a response to the difference in the routing path length.

  One method is to prepare two types of wire harnesses in which the length of the wire bundle is adapted to the length of each routing path in advance, and select the wire harness to be used according to the position of the auxiliary equipment. is there.

  Another method is to share one type of wire harness that has been manufactured according to the longer routing route length in advance, and connect the wire harness to the accessory position of the shorter routing route length. In this case, the extra length of the wire harness is absorbed by routing to an auxiliary clamp or the like additionally provided near the routing route.
