ABSTRACT:
An anti-jackknifing hitch assembly (12) (“assembly”) includes a hitch (18), a tongue (20), two resilient members (22a,22b), and a routing member (24). The hitch (18) is attached to a tow vehicle (10). The tongue (20) extends from a trailer (16) and is attached to the hitch (18). The tongue (20) pivots about a pivot axis (34) within a predetermined range of articulation (52) defined by the resilient members (22a,22b). In particular, resilient members (22a,22b) respectively connect end portions (36a,36b) of hitch (18) to front corner portions (40a,40b) of trailer (16) and are sized for preventing over-articulation. Routing member (24) assists resilient members (22a,22b) in applying a restoring moment about the pivot axis (34). Namely, the routing member (24) extends from the hitch (18) or tongue (20) adjacent to pivoting axis (34). The routing member (24) includes attachment members (48a,48b) with resilient members (22a,22b) extending therethrough.
