Structural unit having net member incorporated therein, seat and method for treating end section of net member

摘要

A structural unit has a net member (10) incorporated therein in such a manner that local application of undue force to the net member is prevented, to thereby increase reliability of the net member (10). An end section (15') of a net member (10) of a three-dimensional structure is treated so as to be reduced in cushioning characteristics and increased in hardness as compared with a portion of the net member positioned away from the end section (15'). A frame (30) constituting a part of the structural unit is provided with an end holding member (20) so that an insertion port of an insertion gap (21) of the end holding member (20) is arranged in a particular direction or posture, resulting in the end section (15') being readily held in the holding member (20) by merely inserting the end section (15') in the insertion gap (21). The end (15') is entirely inserted into the insertion gap, so that application of load to the end section (15') may be carried out in a two-dimensional manner rather than a spot-like manner. This prevents local application of load to the net member (10), to thereby protect the net member from danage. <IMAGE>
