Abstract
Official abstract text for this publication.
A heater unit includes a pair of substrates formed from a polymeric foam and a cord-shaped heater sandwiched between the pair of substrates. The thickness of a region of each of the substrates at which the cord-shaped heater is disposed is thinned relative to other regions of the substrates in such a manner as to be shaped to the cord-shaped heater and thus the heater unit forms a flat shape. In the heater unit, the substrates are bonded together by an adhesive layer that is composed only from a pressure-sensitive adhesive.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a heater unit comprising: providing a first substrate and a second substrate, each of which is formed from a polymeric foam, and a cord-shaped heater; arranging the first substrate on a plurality of hook members, which are movable downwardly such that the hook members penetrate the first substrate; arranging the cord-shaped heater in a predetermined pattern on the first substrate by winding the cord-shaped heater around the hook members one after another; laying the second substrate over the first substrate; and applying heat and pressure to the first and second substrates by a flat plate such that the hook members move downwards and the first and second substrates sandwich the cord-shaped heater and such that a thickness of a region of each of the substrates at which the cord-shaped heater is disposed is thinned relative to other regions of the substrates in such a manner as to be shaped to the cord-shaped heater such that the heater unit forms a flat shape. 2. The method for manufacturing a heater unit as set forth in claim 1 wherein the pair of the substrates are bonded together by an adhesive layer that is composed only from a pressure-sensitive adhesive. 3. The method for manufacturing a heater unit as set forth in claim 1 wherein the cord-shaped heater includes on an outmost layer thereof a thermal fusible region. 4. The method for manufacturing a heater unit as set forth in claim 1 wherein: the pair of the substrates are bonded together by an adhesive layer that is composed only from a pressure-sensitive adhesive; and the cord-shaped heater includes on an outmost layer thereof a thermal fusible region.
