An automotive door-hole-sealing material reduces noise to be generated by contact between the sheeted foam elastic material and the protrusion, and, moreover, improves quietness inside the passenger compartment with high sound absorption performance and sound insulating effect. The automotive door-hole-sealing material 1 includes a resin sheet 2, and a sheeted foam elastic material 3. The resin sheet 2 has a through hole 2c formed in association with a protruding end of the impact absorbing material 105. In a side view, the sheeted foam elastic material 3 has a portion relaxing within an inner periphery of the through hole 2c of the resin sheet 2.

This application claims priority to Japanese Patent Application No. 2016-195467 filed on Oct. 3, 2016, the entire disclosure of which is incorporated by reference herein.
The present disclosure relates to an automotive door-hole-sealing material for sealing, for example, an opening formed on an inner panel of an automotive door. In particular, the present disclosure belongs to a technical field of a structure which allows the automotive door-hole-sealing material to be attached to an inner panel of the automotive door having a protrusion protruding from the opening on the inner panel in an inward-outward direction of a passenger compartment.
An inner panel of an automotive door has, for example, a work opening for securing various parts inside the door and an opening for installing a speaker. To cover these openings, a door-hole-sealing material is attached to the inner panel.
FIG. 1 is a side view of an automotive door to which an automotive door-hole-sealing material according to an embodiment is attached. The automotive door is observed from an inner panel, and a door trim and an impact absorbing material are omitted from the automotive door.
FIG. 2 is a cross-sectional view taken along a line II-II of FIG. 1, illustrating the door trim and the impact absorbing material.
FIG. 3 is a side view of the automotive door-hole-sealing material observed from the inside of a passenger compartment.
An embodiment of the present disclosure will be described in detail below with reference to the drawings. The following description of an advantageous embodiment is only an example in nature, and is not intended to limit the scope, applications or use of the present disclosure.
FIG. 1 is a side view of an automotive door 100 to which an automotive door-hole-sealing material 1 according to an embodiment of the present disclosure is attached. The automotive door 100 is observed from an inner panel. FIG. 1 omits a door trim 104 and an impact absorbing material 105 illustrated in FIG. 2. The automotive door 100 is for opening and closing a not-shown door opening formed on a side of a passenger car. The automotive door 100 has a front end rotatably secured to a pillar of the body via a door hinge.
The automotive door 100 includes at least a door body 101 which is a lower portion of the automotive door 100, a sash 102 which is an upper portion of the automotive door 100, a door glass 103, the door trim 104 illustrated in FIG. 2, and the impact absorbing material (a protrusion) 105 illustrated in FIG. 2. The sash 102 holds a circumferential edge of the door glass 103, and guides the door glass 103 in a vertical direction. This sash 102 may be omitted.
