DEFINITION

Classification: 267/140.11

Including energy absorbing means or feature (e.g., supplemental vehicle equipment, such as motor mount, seat, etc., including additional fluid or friction energy absorber):

(under subclass 136) Structure wherein a means or feature, distinct from a resilient means, absorbs mechanical energy from a vibrating component, converts such absorbed energy to another form of energy, such as heat and thereby damps the absorbed energy.

(1) Note. A mere spring, acting alone or in concert with others, is not considered an energy absorbing member for this subclass as the energy transferred is not changed in form or dissipated but returned almost in full to the vibrating member.

(2) Note. Spring devices of the supporting type useful to cushion relative movement between vehicle parts and which do not involve substantial modification of the vehicle structure are not found herein and in the indented subclasses, but are found in other subclasses within this class.

(3) Note. Devices in this and the indented subclasses include vehicle engine mounts many of which include hydraulic damping.
