摘要

The hinge has a hinge part (1) guided displaceably in a bow-side housing (2) in a bow longitudinal direction, and a U-shaped sliding part (4) that projects from the hinge part in a displacement direction. The hinge part having the sliding part includes a passage opening (16) running in the longitudinal direction of a coiled spring (14). A housing-side buttress (13) is screwed through the passage opening of the hinge part running coaxially to the coiled spring into a female thread (11) of the housing that is coaxial to the coiled spring.
