DEFINITION

Classification: 180/282

Responsive to sensing of acceleration, deceleration, or tilt of vehicle:

(under subclass 271) Vehicle wherein the means responds to the determination of or the reaction to (a) a change in the velocity of travel of the vehicle or (b) a tipping movement of the vehicle in either a side-to-side or a forwardly-rearwardly direction.

(1) Note. The sensing frequently is that accomplished by a gravity-sensitive device (e.g., a mercury switch, a pendulum), but may be, instead, that of a less sophisticated device such as a mechanical linkage serving to transfer the effect of a physical force or movement.

41, as explained in the reference thereto appearing in subclass 271 above.

172, for a motor vehicle provided with means which is responsive to the speed of the vehicle for maintaining its speed at, or preventing it from exceeding, a particular value and wherein the means includes a device which is responsive to centrifugal force, which device may be, as explained in (1) Note of that subclass (172), a pendulum.

274+, for a motor vehicle provided with a safety-promoting means which is responsive to the engagement of a portion of the perimeter of the vehicle with an external object (e.g., collision-caused deceleration).

281, for a motor vehicle provided with a safety-promoting means which comprises either a movable closure member or a fastening device therefor which is responsive to forward or rearward movement, or variations therein, of the vehicle. 290, for a motor vehicle provided with a safety promoting means which is responsive to the weight of a cargo load transported by the vehicle; in the instance of a vehicle which is caused to tilt by the weight of the load applied, classification is here (subclass 282) if the means responds to the tilting rather than, or in addition to, the weight of the load.

5.5+, especially subclasses 5.501+ for a general utility land vehicle including an active suspension responsive to a force encountered while the vehicle is in surface traversing motion; subclasses 124.103, 124.104+, and 124.106+ for a general utility wheeled land vehicle suspension arrangement specifically provided to prevent adverse disposition of the

vehicle body, chassis, or frame; subclasses 734+ for a general utility wheeled land vehicle including an inflatable passenger restraint responsive to a condition of the vehicle; subclass 753 for a general utility wheeled land vehicle passenger safety guard attachment in the nature of a padded or cushioned member wherein the member is positionable by an automatic actuator; or subclass 755 for a general utility wheeled land vehicle attachment preventing the vehicle from tilting or tipping beyond a given point.
