Vehicle seat

Abstract

A vehicle seat having: a seat cushion and a seat back formed by covering a surface of a seat pad with a top cover member; a plurality of air holes which penetrate the seat pad to reach a surface of the top cover member; a plurality of air outlets which project from a surface of a duct to be connected to the air holes; and an air blower to pressure and feed air inside a vehicle compartment to the air holes through the duct and the air outlets, wherein a member which has an elastic modulus larger than that of the seat pad forming the seat cushion is interposed between the seat cushion and the duct.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a vehicle seat having an air conditioning function. [0003] 2. Description of the Related Art [0004] Recently, there is known a vehicle seat having an air conditioning function in which a plurality of air holes are provided in a top cover member of a seat cushion and a seat back of the vehicle seat, and air from an air blower is ejected from the air holes (refer to JP-Tokukaihei-10-297274). [0005] The vehicle seat disclosed in JP-Tokukaihei-10-297274 is schematically configured such that the plurality of air holes are provided to penetrate a top cover member, a cover pad and a pad forming the seat cushion and the seat back, an air blower, an intermediate duct and a seat cushion air exhaust duct are arranged on a lower surface of the seat cushion, and a seat back air exhaust duct is arranged on a back surface of the seat back. [0006] A plurality of air outlets which slightly project fr...

AI Technical Summary

Benefits of technology

[0008] The present invention has been achieved in view of the above problem, and an object of the present invention is to provide a vehicle seat which is capable of suppressing deterioration of comfortable feeling when sitting in the seat due to a duct arranged on a lower surface of a seat cushion.

[0015] According to the vehicle seat, a member which has elastic modulus larger than that of the seat pad forming the seat cushion is interposed between the seat cushion and the duct, so that in the case where the front portion of the seat cushion is deformed due to the downward compressing force from a thigh of a passenger when the passenger sits in or pushes a pedal, the member us elastically deformed to encompass the circumference of the duct. Thus, the passenger does not feel uncomfortable due to the interposed duct, thereby enabling to prevent to lose a comfortable feeling when sitting in the seat, and absorbing the impact to the duct by the weight of the passenger. Further, deformation of the front portion of the seat cushion in the vertical direction (vertical stroke) can be secured due to the elastic deformation of the member.

[0016] Consequently, a vehicle seat which is capable of suppressing deterioration of comfortable feeling when sitting in the seat due to the duct arranged on the lower surface of the seat cushion can be obtained.

[0018] According to the vehicle seat, the seat pad comprises elastomeric resin formed by foamed polyurethane or flexible urethane foam, and the member having elastic modulus larger than that of the seat pad is formed by elastomeric resin which is formed by foamed polyurethane or flexible urethane foam having elastic modulus larger than that of the foamed polyurethane or the flexible urethane foam used for the seat pad, so that the structure capable of obtaining the effect specifically described above can be applied.

Problems solved by technology

However, in a vehicle seat having a normal air conditioning function including one disclosed in JP-Tokukaihei-10-297274, the duct is arranged at the lower surface of the seat cushion, so that when a passenger sits in or pushes a pedal, the passenger may feel uncomfortable due to the duct, thereby losing a comfortable feeling to sit in, or damaging the duct due to the impact by the weight of the passenger's body.
