Abstract
Abstract A safety belt webbing emergency locking apparatus of the type having a vehicle inertia sensor actuated safety belt locking means for preventing safety belt webbing protraction relative to the apparatus, said locking means being biased to a webbing clamping position characterised in that the locking means is normally held in a belt release position by releasable retaining means, vehicle inertia sensor means for operating said releasable retaining means to release said clamping means to allow said clamping means to clamp said webbing preventing further movement thereof, and automatically operating reset means for resetting said retaining means to move said clamping means to said webbing release position and hold it in said position in response to operation of a part of the vehicle in predetermine manner.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
A safety belt webbing emergency locking apparatus of the type having a vehicle inertia sensor actuated safety belt locking means for preventing safety belt webbing protraction relative to the apparatus, said locking means being biased to a webbing clamping position characterised in that the locking means is normally held in a belt release position by releasable retaining means, vehicle inertia sensor means for operating said releasable retaining means to release said clamping means to allow said clamping means to clamp said webbing preventing further movement thereof, and automatically operating reset means for resetting said retaining means to move said clamping means to said webbing release position and hold it in said position in response to operation of a part of the vehicle in predetermine manner.
Claim 2
Dependent Claim
125 words
A safety belt webbing emergency locking apparatus of the type having a vehicle inertia sensor actuated safety belt locking means for preventing safety belt webbing protraction relative to the apparatus, said locking means being biased to a webbing clamping position characterised in that the locking means is normally held in a belt release position by releasable retaining means, vehicle inertia sensor means for operating said releasable retaining means to release said clamping means to allow said clamping means to clamp said webbing preventing further movement thereof, and automatically operating reset means for resetting said retaining means to move said clamping means to said webbing release position and hold it in said position in response to operation of a part of the vehicle in predetermine manner.
Claim 3
Dependent Claim
129 words
Apparatus according to Claim 1 wherein said retaining means includes an actuator link pivotally mounted on said apparatus with one end connected to said belt locking means and having an opposite end, a trigger link having one end pivotally mounted on said apparatus and a free end, said free end having a contact surface engaging a part of said inertia sensor means, and an overcentre acting link connected between said actuating link opposite end and said trigger link free end to normally hold said actuator link against rotative movement until said overcentre acting link is moved in a predetermined manner by said trigger link, said trigger link being moved by said inertia sensor means when the latter senses a change in vehicle inertia of more than a predetermined amount.
Claim 4
Dependent Claim
26 words
Apparatus according to Claim 2 wherein the automatically operating reset means operates on said trigger link to reset the retaining means in the belt release position.
Claim 5
Dependent Claim
43 words
Apparatus according to Claim 1, 2 or 3 wherein said automatically operating reset means for resetting said retaining means is arranged to automatically operate in response to operation of a part of the vehicle such as opening of a door of said vehicle.
Claim 6
Dependent Claim
40 words
Apparatus according to Claim 4 wherein said reset means comprises a door operated switch and means for moving said trigger link contact surface into reset engagement with said inertia sensor means when said door is moved to actuate said switch.
Claim 7
Dependent Claim
114 words
Apparatus according to any preceding claim wherein said safety belt locking means includes clamping means having one or more wedge shaped clamp members for clamping directly upon the safety belt webbing and wherein said actuator link one end is connected to at least one of said one or more wedge shaped clamp members whereby actuation of said inertia sensor means against said trigger link contact surface of more than a predetermined amount causes said overcentre acting link to move an amount freeing said actuator link to move under an associated spring bias to operate said one or more wedge shaped members of said clamping means into clamping position relative to said safety belt webbing.
Claim 8
Dependent Claim
69 words
7 . Apparatus according to any preceding claim wherein said automatically operating reset means include an electrical solenoid means for moving said trigger link to a reset position for said releaseable retaining means and electrical circuitry and switch means are provided for operating said electrical solenoid means to move said trigger link to said reset position in response to operation of swich means by opening of the vehicle door.
Claim 9
Dependent Claim
58 words
Apparatus according to any of Claims 1 to 6 wherein said reset means includes a slide rod normally biased by an associated spring toward a position projecting outwardly of an associated switch body and a cable connected between said slide rod and said trigger link for moving the trigger link to a reset position for said retaining means.
