Door leaf for use in e.g. bus, has sensitive, thin surface heating elements arranged inside leaf between core material of inner-lying core layer and outer-lying cover layers, where element has partial elements separated from each other

摘要

#CMT# #/CMT# The leaf (1) has sensitive, thin surface heating elements (3, 3') arranged inside the leaf between a core material (4a) of an inner-lying core layer (4) and outer-lying cover layers (5, 5'). The heating element is arranged on the side of the core material directing to an interior of a rail vehicle and/or to a passenger compartment of the rail vehicle. The heating element includes partial elements (3a-3d, 3a'-3d'), which are separated from each other. A temperature sensor is arranged at the heating elements and/or at one of the cover layers. #CMT#USE : #/CMT# Door leaf for use in an outer door of a vehicle i.e. rail vehicle (all claimed) such as bus and airplane. #CMT#ADVANTAGE : #/CMT# The sensitive, thin surface heating elements are arranged inside the leaf, so that the heating element is optimally protected, thus reducing the temperature variation between the surface temperature of the door leaf and the middle ambient temperature. The door leaf is arranged in a space saving manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded perspective view of a door leaf. 1 : Leaf 3, 3' : Surface heating elements 3a-3d, 3a'-3d' : Partial elements 4 : Inner-lying core layer 4a : Core material 5, 5' : Outer-lying cover layers.
