Abstract
Abstract A protective device for the passengers of vehicles, especially of motor vehicles which are equipped with gas cushions adapted to be automatically inflated in case of an accident; the hearing passages in the ears of the passengers are thereby partially or completely closed off by these protective devices when the vehicle is so strongly decelerated that the actuating mechanism for the gas cushions is triggered off and/or when the pressure increase occurring as a result of the inflation of the gas cushions in the vehicle interior exceeds a predetermined value.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
179 words
A protective device for the passengers of vehicles, especially motor vehicles, which are equipped with gas cushion means automatically inflatable in case of an accident, characterized in that the protective device provided for a vehicle passenger comprises valve means for at least partially closing the hearing passage in the ear of the passenger and including further means for actuating said valve means in response to a control magnitude reflecting at least one of predetermined deceleration of the vehicle and predetermined pressure increase occurring in the vehicle as a result of the inflation of the gas cushion means, said valve means being actuated to at least partially close said hearing passage, and in which the triggering pulse for the inflation of the gas cushion means take place by way of an electric energizing circuit closed by a switch means responding to a predetermined vehicle deceleration, characterized in that the protective device is actuated by the closing of the energizing circuit prior to the application of the triggering pulse to an actuating mechanism for causing inflation of the gas cushion means.
Claim 2
Dependent Claim
179 words
A protective device for the passengers of vehicles, especially motor vehicles, which are equipped with gas cushion means automatically inflatable in case of an accident, characterized in that the protective device provided for a vehicle passenger comprises valve means for at least partially closing the hearing passage in the ear of the passenger and including further means for actuating said valve means in response to a control magnitude reflecting at least one of predetermined deceleration of the vehicle and predetermined pressure increase occurring in the vehicle as a result of the inflation of the gas cushion means, said valve means being actuated to at least partially close said hearing passage, and in which the triggering pulse for the inflation of the gas cushion means take place by way of an electric energizing circuit closed by a switch means responding to a predetermined vehicle deceleration, characterized in that the protective device is actuated by the closing of the energizing circuit prior to the application of the triggering pulse to an actuating mechanism for causing inflation of the gas cushion means.
Claim 3
Dependent Claim
35 words
A protective device according to claim 1 characterized in that said further means is operable in response to a predetermined deceleration of the vehicle and in response to a predetermined pressure increase inside the vehicle.
Claim 4
Dependent Claim
30 words
A protective device according to claim 1 characterized in that the triggering pulse is operable to bring about the ignition of an explosive charge forming part of the actuating mechanism.
Claim 5
Dependent Claim
27 words
A protective installation according to claim 3, characterized in that a delay means is arranged in a line for the triggering pulse leading to the explosive charge.
Claim 6
Dependent Claim
18 words
A protective device according to claim 4, characterized in that said delay means is an RC circuit element.
Claim 7
Dependent Claim
45 words
A protective device according to claim 5, characterized in that said protective device is incorporated in a protective helmet having an open connecting passage for connecting the hearing channel of a passenger ear with the outside and operable to be closed by said valve means.
Claim 8
Dependent Claim
29 words
A protective device according to claim 6, characterized in that the helmet includes two connecting passages, one for each ear, and two valve means, one for each connecting passage.
Claim 9
Dependent Claim
45 words
A protective device according to claim 1, characterized in that said protective device is incorporated in a protective helmet having an open connecting passage for connecting the hearing channel of a passenger ear with the outside and operable to be closed by said valve means.
Claim 10
Dependent Claim
29 words
A protective device according to claim 8, characterized in that the helmet includes two connecting passages, one for each ear, and two valve means, one for each connecting passage.
