Specific embodiment

Fig. 1 shows the roof 10 for being configured to the vehicle of passenger vehicle.Roof 10 includes opaque (solid) top of car 12, roof opening 14 is formed in the opaque top of car.Roof opening 14 can pass through the sliding of roof opening system 18 Top cover 16 selectively closes off or least partially open.

The sliding roof 16 of roof opening system 18 respectively the either side of the vertical longitudinal median plane of roof correspondingly It is provided with shift movement mechanism 20A and 20B, shift movement mechanism 20A and 20B to be guided in guide rail 22A and 22B respectively, lead Rail 22A and 22B extends on the longitudinal direction of roof or vehicle and is arranged along the respective side edges of roof opening 14.

Guide rail 22A and 22B are the curb girders of roof frame 24, and are connected each other at its front end by front baffle component 26 It connects, front baffle component 26 forms the lateral frame element of roof frame 24, and lateral frame element is prolonged in the transverse direction of roof It stretches.Roof frame 24 is substantially mirror symmetry relative to the vertical longitudinal median plane of roof, thus for the sake of clarity, Following description will be basically limited to guide rail 22B, and the direction of advance relative to the vehicle discussed is arranged in left side.Relative to The guide rail 22A that right side is arranged in the preceding direction of travel of the vehicle discussed is similarly apparent from description.

There is extremity piece 28 in its transitional region to front baffle component 26 from can be seen that guide rail 22B in Fig. 2 and Fig. 3, Extremity piece 28 is separately shown in fig. 4 to fig. 6.Extremity piece 28 (it is injection molding plastic components) includes promoting sliding guide 30, when sliding roof 16 is moved to open position from closed position, sliding part is guided in promoting sliding guide 30, from And the leading edge of sliding roof 16 is allowed to be promoted relative to opaque top of car 12.For the extremity piece as sliding guidance component 28, in order to be fixed on the leader 32 of guide rail 22B (leader 32 is extrusion aluminum-type material), extremity piece 28 include latch and Position lug 34.In order to which guide rail 22B is connected to front baffle component 26, extremity piece 28 has screw openings 36.

In order to drive shift movement mechanism 20A and 20B, roof opening system 18 has drive cable 38A and 38B, they By shared driving motor 40 or its pinion gear driving.Drive cable 38A and 38B are respectively via the cable in front baffle component 26 Guiding piece is directed into the cable pipe 42 of extremity piece 28 and is directed into the leader 32 of guide rail 22A and 22B therefrom Respective cable pipeline in and be each all connected to the corresponding shift movement mechanism 20A respectively in guide rail 22A and 22B and The driving sliding block (not shown) of 20B.

Due to the design of cable pipe 42, cord guiding elements are constituted by the extremity piece 28 of injection moulding manufacture.In addition to cable Except spool road 42, the second cable pipe 44 is formed in extremity piece 28, is used to guide the driving cable of the mask system of roof 10 Line.

Cable pipe 42 is the alternating cable guide formed by the first wall part 46,48 and the second wall part 50, first Wall part 46,48 limits cable pipe 42 from second side from the first lateral confinement cable pipe 42, the second wall part 50.This has such as Lower effect: drive cable 38B alternately by means of the first wall part 46,48 from the first side and by means of the second wall part 50 from Second side is guided.First wall part 46,48 respectively by with the first notch 52 of corresponding second wall part, 50 relative positioning It separates.Second wall part 50 with the second notch 54 of corresponding first wall part, 48 relative positioning respectively by separating.Limit 46 relative positioning of notch 55 and the first wall part of fixed second wall part 50.

There is the length of about 9mm with the notch 55 of 46 relative positioning of the first wall part.Other notches 52 and 54 are in cable pipe There is the length less than 8mm on the longitudinal direction in road 42.Therefore, small with the length of the notch 54 of 46 relative positioning of the first wall part In the Critical Buckling length of about 10mm, drive cable 38B can basically unfetteredly since the Critical Buckling length Pass through 54 buckling of notch.Meanwhile being less than about the flexion limit of 8.0mm with the length of the notch 55 of 46 relative positioning of the first wall part Length, be lower than the Critical Buckling length, drive cable 38B substantially will not as shown in the dotted line in Fig. 6 buckling.
