AI Technical Summary
⚠Technical Problem
Existing frameless door vehicles face challenges in sealing technology due to the absence of a peripheral frame, requiring seals to withstand both compressive and sliding friction forces, which current methods produce complex, time-consuming, and expensive solutions.
⚗Method used
The use of thermoplastic material seals produced by co-extrusion, featuring longitudinal tubes with integrated sliding layers, allowing for seamless integration and reduced production costs by eliminating the need for additional varnish application.
🎯Benefits of technology
The co-extruded thermoplastic seals provide effective sealing by combining sliding and compressive capabilities, simplifying production and reducing costs while maintaining high performance.

Abstract
A vehicle (10) with frameless doors comprises: - a body (15), - two frameless front doors (12), and - sealing strips mounted in the front openings (16) and capable of ensuring sealing between the body (15) and the doors (12) when the doors (12) are in the closed position, the sealing strips being entirely produced by coextrusion of a thermoplastic material and each comprising a longitudinal tube (60) which is closed along its length and covered with a longitudinal sliding layer (64) with which the window of the corresponding door can interact by bearing and sliding.
