Embodiment Construction

[0021] figure 1 A sliding door 1 is shown with two door leaves 2 which are moved behind an outer door frame lining 4 when the door is opened. exist figure 1 For the sake of simplicity, only the side door frame liner is shown, but there is also a part of the door frame liner above the door ( figure 2 shown in ), which covers the upper area of ​​the door leaf 2. The secondary closing edge (Nebenschlieβkante) 2b and the main closing edge (Hauptschlieβkante) 2a of the door leaf 2 are likewise shown.

[0022] figure 2 shows that it is perpendicular to figure 1 Vertical section A-A of the door leaf plane. exist figure 2 The gap 3 between the outer door frame lining or skin 4 and the door leaf 2 is described in detail in . The door leaf 2 moves perpendicularly to the plane of the drawing during opening and closing. Adjacent to the inner side of the door leaves 2 is a cover plate 7 for a door operator (not shown) which acts on one or each door leaf 2 during opening and clos...

Abstract

The invention relates to a sliding door (1) of a vehicle, particularly of a rail vehicle having at least one door leaf (2), wherein a seal is provided at least in sections in the gap (3) between the door leaf (2) and the outer door trim (4). In order to obtain a better sealing effect, a sealing profile (5, 6) protruding into the gap (3) is provided on the outer door trim (4) and on the door leaf (2), said sealing profile comprising at least one sealing strips (5', 6'), wherein the sealing strips (5', 6') of the sealing profiles (5, 6) are offset relative to each other and cover each other at least partially.

Description

technical field [0001] The invention relates to a sliding door of a vehicle, in particular a rail vehicle. Background technique [0002] In sliding doors, both the upper region of the door leaf and its rear edge (side edge) are hidden behind the outer skin of the door frame, for technical reasons there is a gap between the outer side of the door leaf and said outer skin. Moisture, dirt and small debris can penetrate through this gap into the area above the door leaf or next to the rear edge and possibly reach the area of ​​the sensitive door operator arranged above the door leaf. Increasing ingress of moisture and foreign matter will cause premature wear and require frequent cleaning and maintenance. In addition, noise and drafts can penetrate into the interior of the vehicle through this gap and cause disturbance to the passengers. There is therefore a need to seal this gap as well as possible. [0003] The prior art proposes, for the protection of the door operator, to ...
