Abstract: A hinge assembly including a first hinge leaf hingedly connected to a second hinge leaf by a hinge pin (14), the hinge pin (14) being rotatably mounted in one hinge leaf (12) non-rotatably mounted in the other hinge leaf (11), and a check mechanism (30) operably connected to the hinge pin (14) and said one hinge leaf (12) to releasably hold the first and second hinge leaves (11, 12) at at least one angular position about the hinge axis, the check mechanism (30) including check means (32) resiliently biased in a radial direction relative to the hinge axis and into contact with an annular cam track (34) formed on a reaction member (33), the check means (32) being driven along said annular cam (34) by relative rotation between said first an second hinge leafs (11, 12), the cam track (34) including at desired locations therealong one or more check formations (38) which cooperate with said check means (32) to releasably retain the first and second hinge leafs (11, 12) at a desired angular position relative to one

Abstract: A vehicle hinge assembly (10) for hanging a vehicle door on a vehicle body. The assembly (10) comprises a first hinge leaf (12) hingedly connected to a second hinge leaf (14) by a pivot pin (15). The pivot pin (15) is immovably mounted in one hinge leaf (14) and is rotatably mounted in, and axially withdrawable from, the other hinge leaf (12). Hinge pin retention means (35) is associated with the other hinge leaf (12) for preventing axial withdrawal of the hinge pin (15) therefrom. The hinge pin retention means (35) having hinge pin engagement means (38) movably mounted between first and second positions. The engagement means (38) in its first position engages with the hinge pin (15) to permit rotation of the hinge pin (15) but prevent its axial movement relative to the other hinge leaf (12). The engagement means (38) in its second position is spaced from the hinge pin (15) to permit its axial withdrawal from the other hinge leaf (12).
