Accelerator pedal device
First Claim
1. An accelerator pedal device for use with a fixed member, said device comprising:
- a support bracket mounted on said fixed member;
a stopper member mounted to said fixed member;
a pedal lever having a pivot shaft, said pivot shaft being rotatably supported by said support bracket;
biasing means for biasing said pedal lever in such a given direction that an upper part of said pedal lever approaches said stopper member;
a first auxiliary lever pivotally supported by said pivot shaft, said first auxiliary lever having a first upper portion which is located between said stopper member and said upper part of said pedal lever;
a second auxiliary lever pivotally supported by said pivot shaft, said second auxiliary lever having a second upper portion which is located between said first upper portion and said upper part of said pedal lever;
first lost-motion means which provides a lost-motion of a first given angle between said pedal lever and said second auxiliary lever;
second lost-motion means which provides a lost-motion of a second given angle between said second and first auxiliary levers;
a first switch which is actuated when an intersection angle between said pedal lever and said second auxiliary lever becomes smaller than said first given angle; and
a second switch which is actuated when an intersection angle between said second and first auxiliary levers becomes smaller than said second given angle.

Abstract
An accelerator pedal device comprises a pedal lever having a pivot shaft which is pivotally supported by a fixed support bracket. The pedal lever is biased in such a direction that an upper part of the pedal lever approaches a fixed stopper member. A first auxiliary lever is pivotally supported by the pivot shaft and has a first upper portion located between the stopper member and the upper part of the pedal lever. A second auxiliary lever is pivotally supported by the pivot shaft and has a second upper portion located between the first upper portion and the upper part of the pedal lever. A first lost-motion mechanism is provided between the pedal lever and the second auxiliary lever, and a second lost-motion mechanism is provided between the second and first auxiliary levers. A first switch is arranged to be actuated when an intersection angle between the pedal lever and the second auxiliary lever becomes smaller than a first given angle and a second switch is arranged to be actuated when an intersection angle between the second and first auxiliary levers becomes smaller than a second given angle.
