Abstract

An airbag deployment rate sensor employs a tape or string (34) that is wound on a spool (26; 112) and connected to the fabric of an airbag (17) so that as the airbag deploys, tape or string is pulled from the spool causing it to rotate. A brake (48; 68; 84; 100) is applied to the spool to prevent the buildup of momentum and so the tape and the spool (26; 112) will come to a rapid stop when the tape is no longer being withdrawn from the spool because the portion of the airbag (17) to which the tape is connected has collided with an object. A sensor (62; 66; 80; 96; 130) is positioned to detect rotation of the spool and so to monitor the rate at which tape or string is being withdrawn.
