An automotive hinge assembly adapted to facilitate motion of a closure panel relative to a fixed body structure comprises a door component constructed from two press formed angle brackets structurally connected via a pivot pin and adapted to be mounted to a vehicle closure panel, a body component constructed from two press formed angle brackets structurally connected via a simple formed feature and the pivot pin and adapted to be mounted to a vehicle body structure, such that the pivot pin structurally assembles the two hinge components, facilitates relative rotary motion between them and structurally connects the multiple press formed angle brackets so that the resulting assembly achieves a much higher material efficiency than the prior art with an associated significant cost reduction.

A threaded bolt for a hinge arrangement includes a cylindrical main body. On an outer circumferential surface thereof the cylindrical main body has a first frustoconical projection and a second frustoconical projection, which adjoins the first frustoconical projection. The diameter of a side of the first frustoconical projection that faces toward the second frustoconical projection is smaller than the diameter of a side of the second frustoconical projection that faces toward the first frustoconical projection. The first frustoconical projection comprises at least one tooth on its outer circumferential surface, which tooth protrudes radially beyond an imaginary continuation of the second frustoconical projection.

A maintenance window locking device includes a maintenance window body (1), a maintenance window cover (2), a fastening plate (3), a first limiting mechanism (1a) including a groove, and a roller (3a). The fastening plate (3) includes a fastening plate body and a pin (3c) which are of an integrated structure. The pin (3c) is rotatably connected to the roller (3a). The maintenance window body (1) is hinged to a first end of the maintenance window cover (2). The fastening plate body is rotatably connected to a second end of the maintenance window cover (2). The first limiting mechanism (1a) is located on the maintenance window body (1). The fastening plate body drives the maintenance window cover (2) to move toward the maintenance window body (1). The roller (3a) rolls along the first limiting mechanism (1a) until the roller is clamped into the groove, such that the maintenance window cover (2) and the maintenance window body (1) are tightly attached.

The invention relates to a two-part hinge device for a door or a window, comprising a first housing part (20) and a second housing part (30), which in the assembled state form a door hinge housing (19), and a rod (15) which extends in the first housing part (20) and second housing part (30) along the axial direction (60) thereof, wherein the rod (15) has at least three successivea first, a second and a third-rod sections (16, 17, 18). The first rod section (16) is supported in the first housing part (20) by a clamping element (50), and the third rod section (18) supports the second housing part (30). In the region of the second rod section (17), the rod (15) is adjustable relative to the first housing part (20) in two directions at an angle to each other and independently of each other, and the two directions at an angle to each other are arranged transversely to the axial direction (60) of the rod (15).
