#This application claims priority to Japanese Patent Application No. 2020-050181 filed on Mar. 19, 2020, incorporated herein by reference in its entirety.

#The present disclosure relates to a vehicle seat equipped with a cushion airbag device in a seat cushion.

#In an airbag device described in Japanese Unexamined Patent Application Publication No. 2009-035071 (JP 2009-035071 A), an airbag disposed in a seat cushion of a vehicle seat is inflated and deployed at a time of a frontal collision of a vehicle to raise a seat surface of the seat cushion. With this, the occurrence of a phenomenon in which a waist of an occupant slips forward to pass under a lap belt part of a seat belt (so-called submarine phenomenon) is suppressed. A similar technique is disclosed in Japanese Unexamined Patent Application Publication No. 2010-052535 (JP 2010-052535 A).

#Features, advantages, and technical and industrial significance of exemplary embodiments of the disclosure will be described below with reference to the accompanying drawings, in which like signs denote like elements, and wherein:

#FIG. 1 is a vertical cross-sectional view showing a seat cushion of a vehicle seat according to a first embodiment;

#FIG. 2 is an enlarged perspective cross-sectional view showing a region marked with a reference sign F2 in FIG. 1 in an enlarged manner;

#Hereinafter, a vehicle seat 10 according to a first embodiment of the present disclosure will be described with reference to FIGS. 1 to 3. In each drawing, some reference signs may be omitted in order to make the drawings easier to see. Arrows FR, LH, UP shown appropriately in each drawing respectively show a front direction, a left direction, and an upward direction of a vehicle in which the vehicle seat 10 is mounted. Front-rear, right-left, and up-down directions of the vehicle seat 10 coincide with front-rear, right-left, and up-down directions of the vehicle. Hereinafter, when the front-rear, right-left, and up-down directions are simply used for description, the directions are considered to show directions with respect to the vehicle unless otherwise specified.

#The vehicle seat 10 according to the first embodiment includes a seat cushion 12 on which an occupant (not shown) is seated. A lower end portion of a seat back (not shown) that supports a back of the occupant is connected to a rear end portion of the seat cushion 12, and a headrest (not shown) that supports a head of the occupant is connected to an upper end portion of the seat back.

#The seat cushion 12 includes a cushion frame 14, which is a frame, a cushion pad 30, which is a pad, and a cushion cover 34, which is a cover (cover). The cushion frame 14 has a pair of right and left side frames 16 (the left side frame 16 is not shown in FIG. 1), a pair of front and rear pipe frames 18, 20, and a pan frame 22.
