PAD BODY HAVING HIGH FREQUENCY SEALING PERFORMED ON ELASTIC LAYERS FOR IMPROVED SUPPORT EFFECTS

WIPO Patent Application WO/2018/068451

A1

A pad body having high frequency sealing performed on elastic layers for improved support effects, comprising two first elastic layers (11), two first sealing parts (110), and one outer sleeve layer (12). The first elastic layers (11) consist of multiple twisted and wrapped elastic wires P. The first sealing parts (110) are respectively formed from two corresponding edges of the first elastic layers (11) when fused together by utilizing a high frequency technique, thus allowing the elastic wires at other parts on the first elastic layers (11) to warp outwards. The outer sleeve layer (12) covers the first elastic layers (11). As such, gaps between the elastic wires of the first elastic layers (11) in proximity to the first sealing parts (110) are smaller than gaps between the elastic wires at the other parts; hence, the other parts can provide support of greater fluffiness to a user; also, the first sealing parts (110) solidly prevent the pad body from producing excessive deformation or collapsing after supporting weight.
