AI Technical Summary

Technical Problem

Existing vehicle seats with air ducts for ventilation systems risk feet of rear seat passengers hitting the duct, leading to potential interference and deformation, and require a more compact design to enhance airflow and rigidity.

Method used

A vehicle seat design featuring a retractable duct portion positioned closer to one side frame, with a sloping and widening configuration that avoids passenger feet, includes support members with resin components to reduce impact, and a lower pipe section that connects ventilation passages efficiently.

Benefits of technology

Prevents feet from hitting the duct, allows for a more compact seat design, maintains airflow, and enhances duct rigidity while reducing noise and impact during contact.

Abstract

To provide a vehicle seat that can prevent rear-seat passengers' feet from hitting the duct. [Solution] The vehicle seat comprises a first side frame (right cushion side frame 11), a second side frame (left cushion side frame 11), and a duct D extending from the seat cushion S1 toward the seat back, connecting a blower 70 and an air passage formed in at least one of the seat cushion S1 and the seat back. The blower 70 is located between the first side frame and the center position in the left-right direction between the first side frame and the second side frame (see dashed line). The boundary portion of the duct D located at the boundary between the seat cushion S1 and the seat back (first narrow portion 131, second narrow portion 132, and bellows portion 140) is located in the left-right direction between the left-right outer end of the first side frame and the blower 70.
