Tire pressure sensing device and method for the production thereof
First Claim
1. A tyre pressure sensing device for detecting a tyre pressure in a pneumatic tyre, comprising:
- a housing, comprising at least a contact surface for setting on a rim carrying the pneumatic tyre and containing a pressure sensor;
a retainer fastenable to the rim, carrying the housing; and
a spring element connected to the retainer and connected to the housing;
whereby the spring element is embedded partially into the housing and the housing in the area in which the spring element is embedded, comprises at least one opening into the housing partially or completely sealed by a soft component, which surrounds the spring element partially, the soft component having a reduced hardness and higher elasticity than the housing.

Abstract
The invention relates to a tire pressure sensing device for detecting the tire pressure in a pneumatic tire, comprising a pressure sensor (6) in a housing (1); a tire valve (11) or another retainer to be fastened to the rim, which bears the housing; a spring element (2), which is connected to the tire valve or the other retainer at one end and to the housing (1) at the other end, wherein the spring element is partially embedded in the housing and the housing has at least one opening (4, 5) in the area in which the spring element is embedded, said opening being partially or completely opened up by a soft component (13), which partially surrounds the spring element.
