Abstract
A break-away device includes a lower arm 15 pivotally connected to an upper arm 19 by a coupling 17. The lower and upper arms 15,19 are generally maintained in a rigid, colinear relationship by a spring-biased detent pin 39. When the lower arm 15 undergoes a lateral impact, the detent pin 39 is displaced from a grooved detent recess 37 of the lower arm 15 and rolled about an upper convex surface 31 thereof, thereby permitting the lower arm 15 to pivot about the coupling 17 and break away from the upper arm 19.
