Abstract
Abstract A brake holding system for vehicles, comprising a vacuum and magnetic device including a brake holder, a moon gear having a plurality of teeth, a push rod connected to a master cylinder, a holding switch positioned for easy accessibility near the vehicle operator and a brake releasing switch operatively associated with the accelerator. The brake holding system can be placed into position after the vehicle is stopped, for example, at a stoplight, by actuating a switch. The brake is then automatically unlocked by depressing the accelerator pedal. Also, the driver can pull an emergency handle to mechanically release the brake.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
A brake holding system for a vehicle having, in combination, a brake pedal, an accelerator pedal, a master cylinder, a vacuum system and a power supply, which comprises a moon gear having a plurality of teeth on one side thereof, said moon gear being operably connected to the master cylinder, a spring biased holding unit adapted to engage the teeth of the moon gear, against said spring bias whenever the holding system is activated, an on/off member, a vacuum actuator providing communication between said holding unit and said on/off member, a holding switch communicating with said on/off member for activating said holding unit against said spring bias to engage said moon gear, and a releasing switch communicating with said on/off member for disengaging said holding unit upon the depression of the accelerator pedal.
Claim 2
Dependent Claim
