Description

  The present invention relates to a seat back remote control device for unlocking a seat from a position away from the lock when the vehicle seat is folded.

  Some remote control devices for a seat back are operated by operating an operation lever away from the seat back to fold up the seat cushion. For example, it is known that a connecting portion (connector) is connected to a cable extending from a control lever on the driver's seat side to a seat cushion locking mechanism so that a connection error is prevented. (For example, refer to Patent Document 1).

However, in the prior art (Patent Document 1), the cable (first operation cable, second operation cable) extending from the driver's seat can be seen so that the texture is lowered. It is necessary to hide with an interior member not shown in the neighboring figure. The interior member is desired to be easy to mount.
When the cable is fixed to the seat cushion or the seat back, the cable may come into contact with the seat back and be damaged when the seat cushion is flipped up or when the seat back is tilted forward.
