1. In a passenger restraint system for a motor vehicle, an accelerometer comprising:
- a. a tubular housing;
b. an inertial element made of a ferromagnetic material;
c. a tube disposed in said housing forming an annular space with said housing, said tube defining a path of movement for said inertial element;
d. biasing means for urging said inertial element toward a preselected position on said path, said tube being arranged and constructed to allow said inertial element to move away from said preselected position in the presence of a deceleration of said motor vehicle; and
e. resilient shock absorbing means disposed in said space for supporting said tube.

Abstract
An accelerometer for a passenger restraint system in a motor vehicle includes a housing with tube for defining a path for an inertial element, and a biasing member for urging the inertial element toward a preselected position. A shock absorbent resilient ring is disposed between the tube and the housing and supports the tube.

7. An accelerometer for a passenger restraint system in a motor vehicle comprising:
-
a. a substantially tubular housing; b. an inertial element made of a ferromagnetic material and disposed within said housing; c. tube means disposed coaxially within said housing for defining a path of movement for said inertial element, said tube defining an annular space with an inner surface of said housing; d. biasing means disposed on said housing radially for urging, said inertial element toward a first position in said housing, said inertial element moving away from said first position through said tube when said motor vehicle undergoes an acceleration; and e. shock absorbing means disposed in said annular space for supporting said tube. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)

16. A passenger restraint system for a motor vehicle comprising:
-
a. an air bag system arranged and disposed for restraining a passenger when the motor vehicle experiences a deceleration; b. an accelerometer for sensing said deceleration for activating said air bag inflating system, said accelerometer comprising; i. a housing; ii. an inertial element disposed in said housing; iii. a tube disposed in said housing for defining a path of movement for said inertial element within said housing; and iv. biasing means disposed on said housing radially around said tube for urging said inertia element toward a first position in the absence of said deceleration. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
