DCFirst Claim
1. A position adjustable pedal assembly for a vehicle comprising:
- a stationary bracket fixed to a stationary portion of the vehicle;
a lever connected to said stationary bracket for a pivotal movement relative to said stationary bracket about a first pivot axis;
a pedal arm with a pedal pad at its lower end, said pedal arm connected to said lever for pivotal movement with said lever as one integral unit in response to a depression force applied to the pedal pad;
pedal position adjusting means including a drive member and a driven member, said drive member adapted to be activated by a vehicle driver'"'"'s operation, said driven member mounted on said pedal arm to be selectively driven by said drive member to move in a longitudinal direction of the vehicle along with said pedal arm relative to said lever so as to adjust a position of the pedal pad in the longitudinal direction of the vehicle;
an adjust lever provided on said lever, said adjust lever being allowed a relative movement to said lever and having a connecting member which is adapted to move within a first arc-shaped track in response to the relative movement of said adjust lever;
a second arc-shaped track formed on said adjust lever;
a first linear track formed on said lever and extending in the longitudinal direction of the vehicle;
a first guide member provided on said pedal arm, said first guide member adapted to move within said first linear track, and simultaneously within said second arc-shaped track formed on said adjust lever when said pedal arm is driven to move in the longitudinal direction of the vehicle via said pedal position adjusting means, said movement of the first guide member changing a distance from said first pivot axis to said pedal pad corresponding to a magnitude of the movement of said first guide member and simultaneously allowing said relative movement of the adjust lever to change a position of said connecting member within said first arc-shaped track corresponding to said magnitude of the movement of said first guide member; and
operating member means connected to said connecting member for receiving therefrom the depression force applied to said pedal pad via said pedal arm and said lever and for transmitting said depression force to a vehicle operation system to operate same.

Abstract
In a position adjustable pedal assembly for a vehicle, a pedal pad position is adjustable in a longitudinal direction of the vehicle. A lever is connected to a stationary bracket for a pivotal movement about a pivot axis and is formed with a linear track extending in the vehicular longitudinal direction. A pedal arm is provided with a pedal pad at its lower end and with a guide member at its upper end and is connected to the lever for the pivotal movement with the lever in response to a depression force applied to the pedal pad. An adjust lever is provided on the lever for a relative movement to the lever and is formed with an arc-shaped track. The relative movement of the adjust lever is caused when the guide member moves within the linear track and simultaneously within the arc-shaped track while the pedal pad position is adjusted. The adjust lever is provided with a connecting member which is movable within another arc-shaped track in response to the relative movement of the adjust lever. Accordingly, when the pedal pad position is adjusted to move the guide member, the relative movement of the adjust lever is caused to vary a position of the connecting member corresponding to a magnitude of the movement of the guide member, i.e., corresponding to the variation in a distance from the pivot axis to the pedal pad. The depression force is applied to a vehicle operation system through the connecting member.

11. A position adjustable pedal assembly for a vehicle comprising:
-
a stationary bracket fixed to a stationary portion of the vehicle; a lever connected to said stationary bracket for a pivotal movement relative to said stationary bracket about a first pivot axis; a pedal arm with a pedal pad at its lower end, said pedal arm connected to said lever for pivotal movement with said lever as one integral unit in response to a depression force applied to the pedal pad; pedal position adjusting means including a drive member and a driven member, said drive member adapted to be activated by a vehicle driver'"'"'s operation, said driven member mounted on said pedal arm to be selectively driven by said drive member to move in a longitudinal direction of the vehicle along with said pedal arm relative to said lever so as to adjust a position of the pedal pad in the longitudinal direction of the vehicle; an adjust lever being generally of a Z-shape having a first portion extending generally in a forward direction of the vehicle, a second portion extending generally in a rearward direction of the vehicle and a third portion extending generally vertically to connect said first and second portions, said first portion being connected to said lever at its forward end for a pivotal movement relative to said lever and being connected to a first slide pin at its rearward end, said first slide pin engaging into a first arc-shaped slot formed in said lever for sliding movement therewithin in response to the pivotal movement of said first portion, said second portion being formed with a second arc-shaped slot having a predetermined curvature; operating member means including a link member and an operating rod, said link member being pivotally connected to said first slide pin at its rearward end and pivotably connected to said operating rod at its forward end for receiving the depression force from said first slide pin and for transmitting the depression force to said operating rod to operate a vehicle operation system; and said pedal arm provided with a second slide pin at its upper portion which is inserted into a first elongate slot formed in said lever and extending in the longitudinal direction of the vehicle, and into said second arc-shaped slot such that when said second slide pin slides within said first elongate slot and said second arc-shaped slot in the longitudinal direction of the vehicle so as to adjust the pedal pad position, the cooperation of the second slide pin and the second arc-shaped slot forces said first slide pin to slide within said first arc-shaped slot so as to vary a point of application of the depressed force relative to said link member via said first slide pin, said first arc-shaped slot having a predetermined curvature such that the sliding movement of said first slide pin within said first arc-shaped slot is prevented from displacing said operating rod. - View Dependent Claims (12)
