Guide device (10) for sliding windows of motor vehicles, comprising a channel-shaped weather strip (11) fixed to the motor vehicle body (A) along one side of the window and provided with a rigid core (18) and a pair of converging lips (15, 16) which cooperate with the opposite surfaces of the glass (C), and a runner (23) fixed to an edge of the glass (C) and cooperating slidingly with the rigid core (18) of the weather strip (11), characterised in that: - the rigid core (18) is at least partially embedded in the body of the weather strip (11) and has first and second limbs (19,20) extending in correspondence with the base wall (12) df the weather strip (11) and that side wall (14) of the weather strip (11) facing inwardly of the motor vehicle, respectively, the second limb (20) having an appendage (21) which faces inwardly of the weather strip (11) and has its free end aligned approximately with the longitudinal median plane of the weather strip (11) ; - the zone of convergence of the lips (15, 16) of the weather strip (11) lies in an intermediate plane between the longitudinal median plane and that side wall (13) of the weather strip (11) facing outwardly of the motor vehicle, and - the runner (23) is L-shaped and includes a first arm (25) connected to the glass (C) and a second arm (26) which cooperates slidingly with that surface (22) of the appendage (21) facing the first limb (19) of the rigid core (18), whereby the first arm (25) of the runner (23) cooperates slidingly with the side wall (13) of the weather strip (11) facing outwardly of the vehicle.

Guide device (10) for sliding windows of motor vehicles, comprising a channel-shaped weather strip (11) fixed to the motor vehicle body (A) along one side of the window and provided with a rigid core (18) and a pair of converging lips (15, 16) which cooperate with the opposite surfaces of the glass (C), and a runner (23) fixed to an edge of the glass (C) and cooperating slidingly with the rigid core (18) of the weather strip (11), characterised in that: - the rigid core (18) is at least partially embedded in the body of the weather strip (11) and has first and second limbs (19,20) extending in correspondence with the base wall (12) df the weather strip (11) and that side wall (14) of the weather strip (11) facing inwardly of the motor vehicle, respectively, the second limb (20) having an appendage (21) which faces inwardly of the weather strip (11) and has its free end aligned approximately with the longitudinal median plane of the weather strip (11) ; - the zone of convergence of the lips (15, 16) of the weather strip (11) lies in an intermediate plane between the longitudinal median plane and that side wall (13) of the weather strip (11) facing outwardly of the motor vehicle, and - the runner (23) is L-shaped and includes a first arm (25) connected to the glass (C) and a second arm (26) which cooperates slidingly with that surface (22) of the appendage (21) facing the first limb (19) of the rigid core (18), whereby the first arm (25) of the runner (23) cooperates slidingly with the side wall (13) of the weather strip (11) facing outwardly of the vehicle.
Claim 3
Dependent Claim
33 words
Device according to Claim 1,characterised in that the side wall (13) of the weather strip (11) facing outwardly of the vehicle has internal longitudinal ribs (17) defining sliding guides for the runner (23).
Claim 4
Dependent Claim
198 words
Method for the manufacture of a guide device for windows according to Claim 1 or Claim 2, characterised in that it includes the steps of: - forming a shaped strip element (118) of plastically deformable rigid material, the profile of which reproduces a development of the rigid core (18) of the weather strip (11) in the condition in which the limbs of the core (19,20) are coplanar with each other, - incorporating the plastically deformable element (118) at least partially in a strip-shaped rubber body (111) which is substantially C-shaped and includes a flat central portion (112, 113, 114) defining, in development, the base wall (12) and the side walls (13, 14) of the weather strip (11) and two shaped end edges (115, 116) oriented approximately perpendicular to the central flat portion (112, 113, 114) and each reproducing the profile of one of the lips (15, 16) of the weather strip (11), and - plastically deforming the rubber body (111) and the strip element (118) incorporated therein so as to bend the flat central portion (112, 113, 114) into a U-shape and bring the free ends of the shaped end edges (115, 116) into substantially a mating position.
Claim 5
Dependent Claim
25 words
Method according to Claim 3, characterised in that the strip element of plastically deformable material (118) is incorporated in the rubber body (111) by co-extrusion.
Claim 6
Dependent Claim
40 words
Method according to Claim 3 or Claim 4, characterised in that it further includes the step of coating the inner surface of the rubber body (111) by drop-flocking prior to the step of plastic deformation of the body (111) itself.
