Air-conditioned seat cushion

Abstract

An air-conditioned seat cushion includes a flexible seat cushion body bendable to fit a car seat and having a flexible flat fan mount forwardly extended from the front open side thereof and multiple air channels and air holes for ventilation, a fan affixed to the flexible flat fan mount, a hard fan cowl fixedly mounted in the seat cushion body and having shunt passages arranged in air communication between the air channels of the seat cushion body and the air output port of the fan, and a flow guide pivoted to the fan cowl and coupled to the air output port of the fan for biasing with the fan relative to the fan cowl when the flexible flat fan mount is bent relative to the fan cowl to fit a car seat and for guiding currents of air from the air output port of the fan into the shunt passages and the air channels of the seat cushion body.

1 . An air-conditioned seat cushion, comprising:
 a seat cushion body, said seat cushion body comprising a plurality of longitudinal ribs arranged in parallel, a plurality of air channels defined between each two adjacent longitudinal ribs, a plurality of air holes for communication between said air channels and the space outside said seat cushion body, an accommodation space located on a front side relative to said longitudinal ribs, said accommodation space having a front open side, and a flexible flat fan mount forwardly extended from the front open side of said accommodation space, said flexible flat fan mount being bendable through 90-degrees relative to said seat cushion body to fit a car seat, said flexible flat fan mount comprising air vents cut through top and bottom sides thereof;   a fan affixed to said flexible flat fan mount, said fan comprising a fan motor, an air input port facing said air vents, and air output port opposite to said air input port, and a fan blade assembly coupled to and rotatable by said fan motor for causing outside cooling air to flow through said air vents and said air input port toward said air output port;   a fan cowl fixedly mounted in said accommodation space inside said seat cushion body, said fan cowl comprising a plurality of shunt passages arranged in air communication with said air channels of said seat cushion body; and   a flow guide pivoted to said fan cowl at a front side of said shunt passages and coupled to said air output port of said fan for biasing with said fan relative to said fan cowl when said flexible flat fan mount is bent relative to said fan cowl to fit a car seat and for guiding currents of air from said air output port of said fan into said shunt passages and said air channels of said seat cushion body.   
     
     
         2 . The air-conditioned seat cushion as claimed in  claim 1 , wherein said seat cushion body comprises a bottom cushion pad having formed therein a first part of said longitudinal ribs, said air channels and said air holes, a back cushion pad having formed therein a second part of said longitudinal ribs, said air channels and said air holes, and a plurality of bellows tubes connected between said bottom cushion pad and said back cushion pad for enabling said bottom cushion pad and said back cushion pad to be bent through an angle relative to each other and for guiding currents of air from the air channels in said bottom cushion pad to the air channels in said back cushion pad. 
     
     
         3 . The air-conditioned seat cushion as claimed in  claim 1 , wherein said longitudinal ribs are formed of elastic polymers. 
     
     
         4 . The air-conditioned seat cushion as claimed in  claim 1 , wherein said longitudinal ribs are formed of rubber. 
     
     
         5 . The air-conditioned seat cushion as claimed in  claim 1 , wherein said seat cushion body has a covering layer covered over said longitudinal ribs. 
     
     
         6 . The air-conditioned seat cushion as claimed in  claim 5 , wherein said covering layer of said seat cushion body is prepared from an elastic nonwoven fabric. 
     
     
         7 . The air-conditioned seat cushion as claimed in  claim 5 , wherein said covering layer of said seat cushion body is prepared from leather. 
     
     
         8 . The air-conditioned seat cushion as claimed in  claim 1 , wherein said fan further comprises a power cord for connection to an external power source to provide said fan motor with the necessary working voltage, and a control switch for controlling on/off status and operation speed of said fan motor. 
     
     
         9 . The air-conditioned seat cushion as claimed in  claim 1 , wherein said fan is a side flow fan. 
     
     
         10 . The air-conditioned seat cushion as claimed in  claim 1 , wherein said fan is a suction fan. 
     
     
         11 . The air-conditioned seat cushion as claimed in  claim 1 , wherein said fan is an exhaust fan. 
     
     
         12 . The air-conditioned seat cushion as claimed in  claim 1 , wherein said fan cowl is made of metal. 
     
     
         13 . The air-conditioned seat cushion as claimed in  claim 1 , wherein said fan cowl is made of a hard plastic material.
