Abstract
Abstract A manually operable attachment for a locking mechanism adapted for use in a safety belt retractor for vehicle comprises a pivotable member and a rod secured to one end thereof. In use, the pivotable member is manually actuated by means such as a wire pulling means or an electromagnet. An arm is also added to a sensor for the detection of a change in the velocity of a vehicle. The rod is forced down in association with the pivotal movement of the pivotable member, so that its end gives a push to the arm which, in turn, actuates an intermediate means of the retractor locking mechanism.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
In a locking mechanism for use in a safety belt retractor which includes retractor means normally biased in the webbing-retracting direction while allowing webbing withdrawal, locking means adapted to be placed in an engaging position for preventing webbing withdrawal, sensor means for sensing a change in the speed of the vehicle, and transmitting means for actuating said locking means responsive to said sensor means; the improvement comprising manually operated means for actuating said locking means, said manually operated actuating means comprising a vertically disposed weighted actuating member arranged to actuate said transmitting means independently of said sensor means, a tiltable member holding said actuating member in a normally raised position out of contact with said transmitting means, and means for moving said tiltable member downwardly, thereby allowing said actuating member to contact and actuate said transmitting member, said actuating member being vertically moveable with respect to said tiltable member.
Claim 2
Dependent Claim
149 words
In a locking mechanism for use in a safety belt retractor which includes retractor means normally biased in the webbing-retracting direction while allowing webbing withdrawal, locking means adapted to be placed in an engaging position for preventing webbing withdrawal, sensor means for sensing a change in the speed of the vehicle, and transmitting means for actuating said locking means responsive to said sensor means; the improvement comprising manually operated means for actuating said locking means, said manually operated actuating means comprising a vertically disposed weighted actuating member arranged to actuate said transmitting means independently of said sensor means, a tiltable member holding said actuating member in a normally raised position out of contact with said transmitting means, and means for moving said tiltable member downwardly, thereby allowing said actuating member to contact and actuate said transmitting member, said actuating member being vertically moveable with respect to said tiltable member.
Claim 3
Dependent Claim
16 words
A locking mechanism according to claim 1, in which said actuating member comprises a suspended rod.
Claim 4
Dependent Claim
21 words
A locking mechanism according to claim 2, in which said means for moving said tiltable member is a cable pulling means.
Claim 5
Dependent Claim
23 words
A locking mechanism according to claim 3, which further includes a knob for pulling said cable, said knob being colored for apparent discrimination.
Claim 6
Dependent Claim
19 words
A locking mechanism according to claim 2, in which said means for moving said tiltable member is an electromagnet.
Claim 7
Dependent Claim
23 words
A locking mechanism according to claim 5, which further includes a switch for activating said electromagnet, said switch being colored for apparent discrimination.
Claim 8
Dependent Claim
69 words
A locking mechanism according to claim 1, 2, 3, 4, 5 or 6, wherein said transmitting means comprises a pivotable arm having its fulcrum intermediate the ends thereof and means at one end thereof for causing upward movement of said one end responsive to said sensor, said locking means being operatively connected to said one end, and said actuating member is disposed over the other end of said arm.
