Title: Seat belt retractor
Inventor: FUJIMURA YOSHIICHI
IPC: B60R22/34
Filed: 1992-01-27
Abstract: A seat belt retractor is provided with a first emergency locking means for locking rotation of the reel shaft when a locking member 8 engages a ratchet wheel 7, and a second emergency locking means 5 for gripping the seat belt 1. The retractor has a weakened portion  gamma near a section supporting a shaft 21 via two side walls (2a) 2b of the retractor casing. The shaft 21 supports a rotating member 20 of the belt gripping means. A member 19 of the belt gripping means slides vertically upwards under the belt clamping movement of the rotating member 20, until it breaks an upper-end weakened part (2d, Figs. 6 & 8c) of the casing. Thereafter, the weakened portion  gamma undergoes plastic deformation ( epsilon , Figs. 8a & 10) or rupture when a load exceeding a predetermined value is applied on the seat belt 1 through the rotating member 20 and the shaft 21. The clamping force on the seat bolt 1 is thereby maintained within safe limits when the tension on the belt 1 would otherwise cause the rotating member 20 to apply an excessive clamping force upon the belt 1. <IMAGE>

Title: Measuring temperature within a rotating member
Inventor: WOODWARD ANDREW JOHN
IPC: G01K7/34
Filed: 1992-04-07
Abstract: Apparatus for measuring the temperature within a rotating member has within the rotating member a resonance circuit with a temperature sensitive capacitor and a coil. The coil rotates passed a fixed coil to be transiently inductively coupled thereto. Control means provides a series of square wave pulses to the fixed coil so that the resonance circuit is energised when the coils are close together and a pulse is supplied. In response to the detection by the fixed coil of consequent oscillations within the resonance circuit, whilst the coils remain inductively coupled after the transference of energy therebetween, and before the supply of the next energisation pulse, the control means determines the duration of a predetermined number of the oscillations of the resonance circuit. This duration corresponds to the frequency of the oscillations, and hence represents the temperature of the variable capacitor of the resonance circuit. The control means may include a microprocessor.
