Hinge and check assembly

A hinge and check assembly for pivotally connecting a door member to a fixed frame defining a door opening comprising:

• a die cast magnesium base having two opposed surfaces with aligned coaxial apertures formed therein, and said aligned coaxial apertures defining a hinge axis;
• at least one check profile formed in at least one of said two opposed surfaces;
• an enlarged, integral die cast magnesium strap pivotally connected to said base at said hinge axis and said strap having a plurality of apertures extending longitudinally within said strap and parallel to said hinge axis;
• at least one contact surface partially housed within at least one of said plurality of apertures in said strap for rollingly following said at least one check profile while said strap pivots about said hinge axis to establish at least one predetermined angular check position about said hinge axis and said plurality of apertures permitting insertion of additional contact surfaces;
• and
• means for biasing said at least one contact surface against said at least one check profile.

A hinge and check assembly for pivotally connecting a motor vehicle door to a body of a motor vehicle and checking said motor vehicle door upon said motor vehicle door pivoting between a closed position and an open position comprising:

• a die cast magnesium base connected to said body and having two opposed flanges with aligned coaxial apertures formed therethrough, and said aligned coaxial apertures defining a hinge axis;
• an enlarged integral die cast magnesium strap connected to said door and having a plurality of through bores extending longitudinally through said strap and parallel to said hinge axis;
• a pair of similar check profiles formed in each of said two opposed flanges for establishing two predetermined angular check positions with respect to said hinge axis;
• a pair of similar contact surfaces partially housed within opposite ends of one of said plurality of said through bores in said strap and having one of said pair of similar contact surfaces following one of said pair of similar check profiles in one of said two opposed flanges of said base, and the other of said pair of similar contact surfaces following the other of said pair of said similar check profiles in the other of said two opposed flanges of said base and said plurality of through bores permitting insertion of additional contact surfaces;
• means for spring biasing said pair of similar contact surfaces toward said pair of similar check profiles;
• and
• a pivot pin for pivotally connecting said strap to said base through said coaligned apertures of said base to provide angular rotation of said strap about said hinge axis to establish a door check position corresponding to one of said two predetermined angular check positions.

A hinge assembly having at least two hinges for pivotally connecting a motor vehicle door to a body of a motor vehicle wherein each of said hinges comprises:

• a die cast magnesium base having two opposed surfaces with aligned, coaxial apertures formed therethrough and defining a hinge axis;
• an enlarged, integral die cast magnesium strap having a pivot aperture therein alignable with said coaxial apertures of said base;
• a pivot pin insertable through said pivot aperture of said strap and through said aligned, coaxial apertures of said base;
• said base having at least one of said two opposed surfaces having at least one check profile formed thereon;
• and
• said strap having at least one aperture formed therethrough and spaced radially from said aligned, coaxial apertures.

A hinge and check assembly for pivotally connecting a door member to a fixed frame defining a door opening comprising:

• a die cast magnesium base having a unitary construction with two opposed surfaces having aligned coaxial apertures formed therein, and a mounting portion integral with and extending between said two opposed surfaces, and said aligned coaxial apertures defining a hinge axis;
• means for connecting said base to said fixed frame wherein said connecting means is readily accessible on said mounting portion when said strap is in an open position;
• at least one check profile formed in at least one of said two opposed surfaces;
• a die cast magnesium strap pivotally connected to said base at said hinge axis;
• at least one contact surface partially housed in said strap for rollingly following said at least one check profile while said strap pivots about said hinge axis to establish at least one predetermined angular check position about said hinge axis;
• and
• an axial compression spring housed within said strap and engaging said contact surface for biasing said contact surface against said at least one check profile.
