Abstract
Abstract In a control device for a passenger safety apparatus, the safety apparatus is triggered by a sensor arrangement which responds to a longitudinal and/or transverse acceleration of the motor vehicle. It is also independently triggerable by an additional state-of-motion or moving-condition sensor which is configured to recognize a near weightless state of the vehicle. The safety apparatus is triggered even in an extremely critical state of motion in which the vehicle moves in a manner similar to free fall.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
63 words
A control device for an occupant safety device of motor vehicles, comprising a sensor device responding to at least one of longitudinal and transversal acceleration for triggering the safety device, and an additional moving-condition sensor which solely and independently of the sensor device triggers the safety device only when the motor vehicle is in a substantially weightless condition for a specific time period.
Claim 2
Dependent Claim
63 words
A control device for an occupant safety device of motor vehicles, comprising a sensor device responding to at least one of longitudinal and transversal acceleration for triggering the safety device, and an additional moving-condition sensor which solely and independently of the sensor device triggers the safety device only when the motor vehicle is in a substantially weightless condition for a specific time period.
Claim 3
Dependent Claim
47 words
The control device according to claim 1, wherein a time function element is connected behind the moving-condition sensor, and the safety device is configured to be triggered when the vehicle is in the substantially weightless condition for longer than a switching time of the time function element.
Claim 4
Dependent Claim
27 words
The control device according to claim 1, wherein the moving-condition sensor is a distance sensor which determines a distance of the motor vehicle from a road surface.
Claim 5
Dependent Claim
15 words
A control device according to claim 1, wherein the moving-condition sensor responds to vertical acceleration.
Claim 6
Dependent Claim
16 words
The control device according to claim 1, wherein the moving-condition sensor is a wheel rebound sensor.
Claim 7
Dependent Claim
27 words
The control device according to claim 2, wherein the moving-condition sensor is a distance sensor which determines a distance of the motor vehicle from a road surface.
Claim 8
Dependent Claim
15 words
A control device according to claim 2, wherein the moving-condition sensor responds to vertical acceleration.
Claim 9
Dependent Claim
17 words
The control device according to claim 2, wherein the moving condition sensor is a wheel rebound sensor.
