Description

[Detailed Description of the Invention] This invention relates to a variable operating lever for an automobile transmission.

The position of the knob on the conventional automobile transmission control lever is adjusted to fit an average-sized driver, and the seat's fore-and-aft position and standard reclining seat back angle are adjusted to suit this physique. The position has been determined to be ergonomically optimal based on the standards. However, while the fore-and-aft position of the seat is mainly adjusted according to the length of the driver's legs, the difference in arm length between drivers is on average smaller than the difference in leg length. This operating lever, especially its knob position, will be inappropriate for a driver with a non-average physique. Furthermore, if the seat back of the reclining seat is adjusted to an angle other than the standard angle, the position of the knob will similarly be inappropriate.

In view of the above, this invention is a variable control lever that is configured so that the operating lever, especially its knob, can be adjusted to an optimal position depending on the physique of the driver or the angle of the seatback in a reclining seat. The purpose is to provide an operating lever.

The gist of this invention is that the operating lever is made up of two parts, upper and lower, and the upper operating lever is pivotally connected to the lower operating lever by a shaft in the left and right direction, and an angle adjustment mechanism and an angular displacement mechanism are respectively installed between these two levers. This angle adjustment mechanism includes a locking member having a plurality of notches, and a claw member that is biased by a spring so as to be pressed against the notches and is slidably attached to the upper operating lever. The angle of the upper operating lever relative to the lower operating lever is formed to change depending on the position of the notch to be locked, and the pawl member controls the release of the engagement between the slide rail and the seat track in the mechanism for adjusting the seat back and forth. A control cable is connected to either or both of the slide lever and the reclining lever that controls the release of the seat back of the reclining seat mechanism and the seat, and when the slide lever or the reclining lever is moved to the release side, the claw member is engaged. The angular displacement mechanism is configured to be disengaged from the locking member, and the angular displacement mechanism is configured such that the upper operating lever is biased by a spring with respect to the aforesaid axis and that the upper operating lever is opposed to this biasing force. The other end of the control cable connected to the seat track and/or the reclining seat back is connected to either one or both of the seat track and the reclining seat back, and when the seat track or the seat back is displaced, the upper end of the upper operating lever moves to the same position as the seat track or the seat back. It is formed to be angularly displaced in the direction.

The structure of this invention will be explained below with reference to the illustrated embodiments. FIG. 1 is a schematic diagram of the angular displacement mechanism of this invention, showing the state in which the back and forth movement of the seat 1 is converted into the angular movement of the upper operating lever 2 by the inner wire of the control cable 5. FIG. 2 shows the operating lever in detail, and the lower end of the upper operating lever 2 is rotatably pivoted by a left-right shaft 4 to the upper end of a lower operating lever 3 that projects upward from a transmission box (not shown). A locking member 7 is also fixed to the upper end of the lower operating lever 3 in parallel with the upper operating lever. 7a, 7b, 7c, and 7d are formed so that their center lines point toward the axis of the shaft 4, and a claw piece 9 is fixed to a sleeve 8 that is slidably fitted to the upper operating lever 2 to form a claw member. 10, and the upper operating lever 2

is fixed near the lower end of the link 17, and by pulling the inner wire 5a, the upper operating lever 2 is formed so that its posture (angle) can be displaced in response to the displacement of the seat track 22 or the seat back 29, which will be described later. An angular displacement mechanism is formed.

In FIG. 3, a slide rail 21 is fixed to the floor of a vehicle body (not shown) in the longitudinal direction, and an outer wire 5b is fixed to a protrusion 21a protruding from the right side near the front end of the slide rail 21. The seat track 22 is slidably mounted on the slide rail 21, and has a protrusion 22a protruding near the center of the right side thereof.
The tip of the inner wire 5a is connected to.
A known locking mechanism 24 is attached to a pedestal portion 22b provided near the center of the left side of the seat track 22, and this mechanism rotates a slide lever 26 pivotally connected to a pin 25 clockwise against a spring 27. When the seat is moved, the lock pin 28 comes out of the lock hole 21b arranged in the front-rear direction on the left side of the slide rail 21, and the seat track 22 is released from the slide rail 21. Including this lock mechanism, the slide rail and the seat track constitute a seat longitudinal adjustment mechanism. The tip of the inner wire 13a is connected to the slide lever 26 in front of the pin 25, and the tip of the outer wire 13b is fixed to the protrusion 22d of the base 22b. In the above description, the seat 1 is fixed to the upper surface of the seat track 22, and the angle of the upper operating lever 2 (described later) and therefore the position of the knob 6 change as the seat track 22 moves in the front and back direction. It is configured for an ergonomically optimal position. Furthermore,
