Detailed Description of the Invention [Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractable shift lever device for a vehicle transmission, and more particularly to a vehicle shift transmission in which a floor shift type shift lever for an automobile or the like can be bent at a predetermined position (predetermined range). The present invention relates to an inversion type shift lever device.

[Prior art]

2. Description of the Related Art In recent years, in vehicles such as automobiles, a so-called floor shift type shift lever, in which a shift lever of a transmission is arranged on a vehicle floor between a driver's seat and a passenger seat, has become widespread. Then, a shift lever standing upright from the vehicle floor in the vehicle compartment switches and operates the shift stage of the transmission through a remote control link system (control cable or the like). In a vehicle equipped with a floor shift type shift lever, a driver often gets in and out of the passenger seat side in a place with a small parking space or a place with heavy traffic.
In that case, when shifting from the driver's seat to the passenger's seat side, or when shifting from the passenger's seat to the driver's seat side, the shift lever standing upright from the vehicle floor becomes an obstacle as a protrusion and cannot be easily transferred. Therefore, a shift lever device that has been conventionally provided on a vehicle floor is divided into upper and lower parts, and the shift lever can be bent by connecting both with a pin so as to facilitate the transfer operation of the seat. (For example,
Nos. 56-32887 and 56-42729 are proposed.

[Problems to be Solved by the Invention]

However, in the previously proposed retractable shift lever device, the shift lever is bent in the vehicle front-rear direction (shift operation direction in the automatic transmission, shift direction in the manual transmission) and tilted when the seat is moved. It is composed. Moreover, there is no means for restricting the bending operation position of the shift lever. Therefore, when the shift lever is bent to the front of the vehicle and tilted, the tilted shift lever is likely to be an obstacle on the contrary, especially in a cab-over type vehicle. In addition, when the shift lever is bent rearward of the vehicle and tilted, it interferes with the console box, the parking brake lever, and the like, so that the tilted position of the shift lever cannot be lowered sufficiently, and the shift lever still tends to be an obstacle. It is also conceivable that when the shift lever is bent, the bent portion is exposed and becomes a protrusion, and clothes are hooked on the bent portion when the seat is moved in the vehicle interior. In addition, even if a caution plate with cautions for bending the shift lever is attached, it is possible to bend the shift lever at the neutral position while the engine is running while the vehicle is stopped, and then tilt it down to leave the driver's seat in this state. Conceivable. It is also possible that a part of the body touches the shift lever by mistake when moving the seat. Therefore, it is desirable to take safer measures against such an emergency. Therefore, an object of the present invention is to prevent a shift lever that is folded and tilted when a seat is moved from being a hindrance in a retractable shift lever device for a vehicle transmission, and to further improve safety.

[Means for solving problems]

Therefore, the present invention adopts the following configuration as a means for solving the above problems. That is, according to the present invention, in the above-described retractable shift lever device for a vehicle transmission, a cover member that is attached to a fixed member and covers a bent portion of the shift lever is bent only at a predetermined position to a passenger seat side of the upper lever portion. Is provided with a guide groove for allowing the upper lever portion to be bent, and stopper means for preventing bending of the upper lever portion is provided, and the stopper means is configured to be released when the parking brake is operated. Specifically, referring to FIG. 1 to FIG. 4 and FIG. 16, as an example, a retractable shift lever device for a vehicle transmission includes a shift lever (disposed between a driver's seat and a front passenger seat). 10) is divided into an upper lever part (20) on the shift knob (21) side and a lower lever part (30) on the transmission side, and both lever parts (20, 30) can be bent by the joint means (40). Is bound to. The cover member (70/90) attached to the fixed member and covering the bent portion of the shift lever has a guide groove (allowing the upper lever portion (20) to be bent toward the passenger side only at a predetermined position (P range). 76 ・ 96) has been formed. Further, stopper means (120) for preventing the bending of the upper lever portion (20) is provided. The stopper means (120) is configured to be released when the parking brake is operated.

[Action]

According to the above-mentioned means, at the shift position other than the predetermined position (P range), the upper lever portion (20) of the shift lever is provided.
The guide groove (76/96) formed in the cover member does not match, and the shift lever (10) cannot be bent. When the shift lever (10) is shifted to a predetermined position (P range), the upper lever portion (20) and the guide groove (76/96) formed in the cover member are aligned, and the shift lever (10) is in the bendable position. Become. However, if the parking brake is not operated, the stopper means (120) prevents the upper lever portion (20) from being bent. Then, when the parking brake is operated, the stopper means (120) is released. As a result, the upper lever (2
0) can be tilted toward the passenger seat along the guide groove (76/96). In other words, the shift lever (10) cannot be bent and tilted without operating the Perkin brake. Then, in the state in which the shift lever is tilted, the driver's seat is moved, that is, the driver's seat is moved to the passenger seat side, or the passenger's seat is moved to the driver seat side.

Noh.

【The invention's effect】

As described above, according to the present invention, the shift lever is bent toward the front passenger seat side and is tilted only at a predetermined position. Therefore, the tilted upper lever portion and the shift knob do not project. Therefore, the movement of the seat does not become an obstacle, and the movement of the seat inside the vehicle becomes extremely easy. Further, since the shift lever cannot be tilted without operating the parking brake, it is possible to prevent forgetting to operate the parking brake, which is extremely safe.
