<p>An automotive door hinge assembly is provided with a hold-open device with a leaf spring member (28) carried on a first part (12) of a hinge assembly (10), and a compound roller (50) carried on a second part (14) of the hinge assembly (10), wherein the compound roller (50) engages the leaf spring (28) member with the combination of a flexible and resilient first material portion (54) and a hard, rigid second material portion (52) of the roller assembly during its motion between the door open and door closed positions. Preferably, the hard, rigid second material portion (52) of the roller assembly (50) is made of a single piece spool (52) having a first, reduced diameter, annular shoulder (56) interposed between two, longitudinally spaced, enlarged diameter, annular shoulders (58). To reduce noise, a synthetic bushing (62) is preferably disposed between the spool (52) and a roller pin (60) of the hinge mechanism and the first annular shoulder (56) has a roughened surface engageable with the first material portion (54).</p> |
