Structurally improved seat cushion

Abstract

The present invention relates to a structurally improved seat cushion, comprising a main body which includes a padding part, a backrest part and multiple accordion-shaped vent pipes used to connect the padding and backrest parts. There are guide grooves formed between padding components on the padding and backrest parts, multiple wings extending from two side edges of the padding components and capable of being bent to fit in with a seat adequately and a containing space with an opening at front end of the padding part to fix a wind scooper, while a blower fan is connected with the opening. When the blower fan draws external cooling air into the main body, the cooling air goes quickly out of vent holes along diversion grooves formed by multiple separation boards in the wind scooper, guide grooves and vent pipes, making users feel cool, ventilative and more comfortable when sitting on it.

1 . A structurally improved seat cushion, comprising a main body, a blower fan and a wind scooper, wherein:
 the main body includes a padding part, a backrest part and a multiplicity of hollow accordion-shaped vent pipes connecting the padding part through to the backrest part; both the padding and backrest parts have multiple padding components that are transversely arranged at regular intervals, and guide grooves are established between the padding components to guide airflows, and multiple vent holes are further formed inside these guide grooves for air to blow out of the main body;   there are multiple wings extending from two outer edges of the padding components, in which the wings can be bent to fit in with a proposed seat adequately; the padding part has a containing space with an opening in front of the guide grooves, and the main body is covered by at least one layer of cover;   the blower fan is connected to the opening at the front end of the main body, and consists of a motor and multiple blades; the blower fan is connected with a power wire which is equipped with a control switch set, and is wrapped by a cover; on the surface of the cover, a through hole is opened facing the blower fan for external cooling air to go in, and on the outer side of the through hole, an outlet is established to connect with the opening at the front end of the padding part to guide cooling air into the containing space;   the wind scooper is fixed in the containing space of the main body, and multiple bent separation boards are installed inside the wind scooper; multiple diversion grooves are formed between the separation boards to connect with the opening and guide grooves in the padding part respectively.   
     
     
         2 . The structurally improved seat cushion according to  claim 1 , wherein the main body contains catching grooves, while the vent pipes have convex fasteners at their front and back ends, so that the convex fasteners are fastened into the catching grooves on the padding components for a fixing purpose. 
     
     
         3 . The structurally improved seat cushion according to  claim 1 , wherein the padding part and wings of the main body may be made respectively from foam, foamed substances or elastomeric polymers. 
     
     
         4 . The structurally improved seat cushion according to  claim 1 , wherein the padding part and wings of the main body may be made from rubber or silicon rubber. 
     
     
         5 . The structurally improved seat cushion according to  claim 1 , wherein the wings of the main body are wrapped by four pieces of high density foam along the side edges of the padding parts and backrest parts, and the padding components made from EVA foam on the padding parts and backrest parts are used to separate the wings from the main body, so as to make the wings be freely folded or bent, thus enabling the main body to be easily placed on a proposed seat and lean against the concave bucket-shaped back appropriately. 
     
     
         6 . The structurally improved seat cushion according to  claim 1 , wherein the vent pipes of the main body are made of hollow and flexible materials. 
     
     
         7 . The structurally improved seat cushion according to  claim 1 , wherein the surface of the cover on the padding part of the main body opposite to the padding components is wrapped by a sheet of high density foam as supports and pads of the multiple vent holes, supplemented by a sheet of pierced mesh fabric with dense holes and supporting structural strength. 
     
     
         8 . The structurally improved seat cushion according to  claim 1 , wherein the cover that wraps the main body may be made of soft plastic. 
     
     
         9 . The structurally improved seat cushion according to  claim 1 , wherein the cover that wraps the main body may be made from foam. 
     
     
         10 . The structurally improved seat cushion according to  claim 1 , wherein the cover that wraps the main body may be made of mesh fabric or artificial fibre. 
     
     
         11 . The structurally improved seat cushion according to  claim 1 , wherein the cover that wraps the main body may be made of leather or artificial leather. 
     
     
         12 . The structurally improved seat cushion according to  claim 1 , wherein the power wire of the blower fan can be electrically connected with a proposed power supply or external power source for supply of the electricity required by the seat cushion, and the control switch set is used to start, switch on/off the blower fan or to adjust the air volume. 
     
     
         13 . The structurally improved seat cushion according to  claim 1 , wherein the wind scooper is made of metal materials or with injection molding of plastic.
