Abstract
Abstract In an automotive vehicle having a brake mechanism and a key actuated switching-ignition mechanism to start a power plant, an automotive safety device having a first engaging means for engaging said brake mechanism when said switching-ignition mechanism is deactivated and maintaining said brake mechanism engaged while said switching-ignition mechanism is off, a releasing means for releasing said first engaging means and for maintaining said first engaging means disengaged while said switching-ignition mechanism is on, an actuating means for actuating said releasing means when said key actuates said switching-ignition mechanism and connected to said releasing means by electrical lead means, a vacuum chamber enclosing said electrical lead means and extending from adjacent said actuating means to adjacent said releasing means, and a second engaging means for engaging said brake mechanism when a given vacuum in said vacuum chamber is released and for maintaining said brake mechanism engaged until said given vacuum is restored within said vacuum chamber.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
156 words
In an automotive vehicle having a brake mechanism and a key actuated switching-ignition mechanism to start a power plant, and automotive safety device comprising: a first engaging means for engaging said brake mechanism when said switching-ignition mechanism is deactivated and maintaining said brake mechanism engaged while said switching-ignition mechanism is deactivated; a releasing means for releasing said first engaging means and for maintaining said first engaging means disengaged while said switching-ignition mechanism is activated; an actuating means for actuating said releasing means when said key actuates said switching-ignition mechanism and connected to said releasing means by electrical lead means; a vacuum chamber enclosing said electrical lead means and extending from adjacent said actuating means to adjacent said releasing means; and a second engaging means for engaging said brake mechanism when a given vacuum in said vacuum chamber is released and for maintaining said brake mechanism engaged until said given vacuum is restored within said vacuum chamber.
Claim 2
Dependent Claim
156 words
In an automotive vehicle having a brake mechanism and a key actuated switching-ignition mechanism to start a power plant, and automotive safety device comprising: a first engaging means for engaging said brake mechanism when said switching-ignition mechanism is deactivated and maintaining said brake mechanism engaged while said switching-ignition mechanism is deactivated; a releasing means for releasing said first engaging means and for maintaining said first engaging means disengaged while said switching-ignition mechanism is activated; an actuating means for actuating said releasing means when said key actuates said switching-ignition mechanism and connected to said releasing means by electrical lead means; a vacuum chamber enclosing said electrical lead means and extending from adjacent said actuating means to adjacent said releasing means; and a second engaging means for engaging said brake mechanism when a given vacuum in said vacuum chamber is released and for maintaining said brake mechanism engaged until said given vacuum is restored within said vacuum chamber.
Claim 3
Dependent Claim
39 words
In an automotive vehicle having a brake mechanism and a key actuated switching-ignition mechanism to start a power plant, an automotive safety device as claimed in claim 1 wherein said vacuum chamber at least partially encloses said releasing means.
Claim 4
Dependent Claim
36 words
In an automotive vehicle having a brake mechanism and a key actuated switching-ignition mechanism to start a power plant, an automotive safety device as claimed in claim 1 wherein said releasing means comprising a solenoid means.
Claim 5
Dependent Claim
35 words
In an automotive vehicle having a brake mechanism and a key actuated switching-ignition mechanism to start a power plant, an automotive device as claimed in claim 3 within said vacuum chamber encloses said solenoid means.
Claim 6
Dependent Claim
42 words
In an automotive vehicle having a brake mechanism and a key actuated switching-ignition mechanism to start a power plant, an automotive safety device as claimed in claim 1 wherein said given vacuum in said vacuum chamber directly maintains said second disengaging means.
Claim 7
Dependent Claim
46 words
In an automotive vehicle having a brake mechanism and a key actuated switching-ignition mechanism to start a power plant, an automotive safety device as claimed in claim 1 wherein said actuating means is adjacent said switching-ignition mechanism and is actuated by a portion of said key.
Claim 8
Dependent Claim
45 words
In an automotive vehicle having a brake mechanism and a key actuated switching-ignition mechanism to start a power plant, an automotive safety device as claimed in claim 1 wherein said given vacuum is created and sealed into said vacuum chamber during manufacture prior to installation.
Claim 9
Dependent Claim
45 words
In an automotive vehicle having a brake mechanism and a key actuated switching-ignition mechanism to start a power plant, an automotive safety device as claimed in claim 1 wherein said given vacuum can be maintained in said vacuum chamber by operation of said power plant.
