Joint connection between two plastic parts
First Claim
1. A joint connection (3) comprising two plastic parts, the two plastic part (1, 2) being at least partially relatively rotatable, the joint connection having an outer element (4'"'"') which is formed on a first of the parts and an inner element (5'"'"') which is formed on a second of the parts and which is at least partially located within the outer element (4'"'"'), the outer element (4'"'"') defining a cylindrical circumferential space (7) disposed about an axis and the inner element (5'"'"') being located within the outer element centrally of the circumferential space (7), the joint connection having an axial middle between two zones (I, II) extending substantially along the axis, each zone extending radially through the two plastic parts (1, 2) and comprising a pair of radially opposed flat surfaces (9, 12) and a pair of radially opposed curved surfaces (10, 11) oriented in the axial direction, a cross-section of one zone resembling that of the other zone when rotated through 180°
- relative to the axis.

Abstract
The invention relates to a joint connection (3) between two plastic parts (1 and 2), one part being at least partly rotatable in relation to the other part. According to the invention, the joint connection (3) consists of a shell-form outer element (4) on the one plastic part (1) and an inner element (5), at least partly supported in the outer element (4), on the other plastic part (2), both elements (4) and (5) being made by being injection molded one in the other, from one tool.
