Abstract
Abstract A brake pedal operated manually by the driver, a driving arm connected to a brake cable, and a ratchet wheel driven by a motor are rotatably supported on a pedal shaft. A ratchet member, mounted on the driving arm, is meshed with the ratchet wheel. When the brake pedal is depressed in a direction A, the brake pedal and the driving arm are coupled to each other through a limiting device and the driving arm, with a locking recess 35 1 urged by a locking pin, is turned in the direction A to operate a brake. When the driving arm is otherwise turned in the direction A, only the arm is turned in the direction A, with the brake pedal separated by the limiting device being left at the brake operating position and prevents the operating foot from being caught between the pedal and vehicle body while such driving arm is otherwise turned and such brake is applied.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
134 words
A parking brake system operable by manually operating a brake operating member by a driver, and operable by automatically operating the brake operating member by a drive source, said system comprising limiting means for limiting the movement of at least a portion of the brake operating member toward a brake force applying position of said brake operating member during an automatic operation of the brake operating member by the drive source, wherein said brake operating member comprises a base end-side member connected to the drive source, and a tip end-side member operated by a driver, said base end-side and tip end-side members being pivotally supported by a folding shaft, and wherein during automatic operation of said brake operating member, the limiting means permits the tip end-side member to be folded about the folding shaft.
Claim 2
Dependent Claim
134 words
A parking brake system operable by manually operating a brake operating member by a driver, and operable by automatically operating the brake operating member by a drive source, said system comprising limiting means for limiting the movement of at least a portion of the brake operating member toward a brake force applying position of said brake operating member during an automatic operation of the brake operating member by the drive source, wherein said brake operating member comprises a base end-side member connected to the drive source, and a tip end-side member operated by a driver, said base end-side and tip end-side members being pivotally supported by a folding shaft, and wherein during automatic operation of said brake operating member, the limiting means permits the tip end-side member to be folded about the folding shaft.
Claim 3
Dependent Claim
71 words
A parking brake system according to claim 1, further including a driving member connected to the drive source, said driving member and said brake operating member being capable of engaging with and disengaging from each other through a locking member, and wherein during automatic operation of said brake operating member, the limiting means releases a locking connection through the locking member to separate the brake operating member from the driving member.
Claim 4
Dependent Claim
21 words
A parking brake system according to claim 1, wherein said brake operating member is operated by a foot of a driver.

Claim 6
Dependent Claim
30 words
A parking brake system according to claim 2, further comprising a cam member, and the locking connection of said locking member is released by an action of said cam member.
Claim 7
Dependent Claim
33 words
A parking brake system according to claim 1, further comprising a casing, a return spring stretched between said tip end-side member and said casing, and a folding spring mounted on said folding shaft.
Claim 8
Dependent Claim
28 words
A parking brake system according to claim 1, further comprising a stopper mounted on said base end-side member for limiting a turning movement of said tip end-side member.
Claim 9
Dependent Claim
18 words
A parking brake system according to claim 3, wherein said system is mounted on a vehicle body panel.
Claim 10
Dependent Claim
148 words
A parking brake system operable by manually operating a brake operating member by a driver, and operable by automatically operating the brake operating member by a drive source, said system comprising: limiting means for limiting the movement of at least a portion of the brake operating member toward a brake force applying position of said brake operating member during an automatic operation of the brake operating member by the drive source; and a driving member connected to the drive source, said driving member and said brake operating member being capable of engaging with and disengaging from each other through a locking member, and wherein during automatic operation of said brake operating member, the limiting means releases a locking connection through the locking member to separate the brake operating member from the driving member, wherein said driving member and said brake operating member are supported on a common shaft.
Claim 11
Dependent Claim
148 words
A parking brake system operable by manually operating a brake operating member by a driver, and operable by automatically operating the brake operating member by a drive source, said system comprising: limiting means for limiting the movement of at least a portion of the brake operating member toward a brake force applying position of said brake operating member during an automatic operation of the brake operating member by the drive source; and a driving member connected to the drive source, said driving member and said brake operating member being capable of engaging with and disengaging from each other through a locking member, and wherein during automatic operation of said brake operating member, the limiting means releases a locking connection through the locking member to separate the brake operating member from the driving member, wherein said driving member and said brake operating member are supported on a common shaft.
