no. 1 Embodiment approach
[0092] Next, a first embodiment of the present invention will be described with reference to the drawings.
[0093] [the whole frame]
[0094] A vehicle seat as an example of a vehicle seat of the present invention has a structure as follows: figure 1 The outer side of the shown seat frame 1 is covered with a cushion made of polyurethane foam or the like. The seat frame 1 has a seat back frame 2 and a seat frame 3 . In addition, in the present invention, front and rear, left and right, up and down, etc. are based on the occupant seated on the seat.
[0095] like figure 2 As shown, the seat bracket 3 mainly has: a slide rail slider device 10, which is used as an example of a mounting bracket for mounting the seat on a vehicle body (an example of a vehicle body); a height adjustment mechanism 20, which It is used to adjust the height of the seat support surface; the basic bracket; the movable bracket 40; the tightening device 50, which is used as an example of the occupant ...
no. 2 Embodiment approach
[0249] Refer below Figure 20 ~ Figure 37 A second embodiment of the present invention will be described.
[0250] In addition, the second embodiment can be implemented in combination with the first embodiment, or the second embodiment can be implemented alone.
[0251]In addition, the components, arrangement, etc. to be described below are not intended to limit the present invention, and it is of course possible to make various changes in accordance with the gist of the present invention as in the above-mentioned embodiment.
[0252] In the second embodiment, the occupant protection device is a safety belt having the following components: a shoulder safety belt, which restrains the occupant sitting on the vehicle seat from the shoulder to the waist; occupant's waist.
[0253] For example, Japanese Invention Patent Laid-Open No. 2003-1523922 discloses the following technology: when a vehicle collides, the following device is operated at the same time. The waist restraint de...

Abstract
A vehicle seat is configured in such a manner that, when a collision from the front relative to the occupant occurs, the seat surface of the seating section moves. The vehicle seat is provided with: a base frame which is supported on the seating section at a position thereof which is on the vehicle body side; a movable frame (40) which is movable relative to the base frame; at least one driving force generating member (second gas cylinder (61)) which is activated in a frontal collision; and one or more power transmitting members for transmitting the driving force of the driving force generating member. At least one of said one or more driving force generating members is disposed so as to face the movable frame (40), and the movable frame (40) has a recess (42A) provided at the portion thereof which faces the driving force generating member.
Description
technical field [0001] The present invention relates to a vehicle seat such as a vehicle seat, in particular to a vehicle seat whose structure is based on an occupant and whose seat support surface (seat surface, the same below) moves when a frontal collision occurs . Background technique [0002] A vehicle seat is known in which a seat support surface of a seat portion moves rearward when a frontal collision such as a frontal collision occurs to the vehicle. For example, Patent Document 1 discloses a vehicle seat in which a seat support surface is moved rearward by a tightening device (air cylinder) whose axis is oriented in the left-right direction. [0003] In addition, Patent Documents 1 and 2 disclose a vehicle seat in which a seat belt is immediately tightened by a tightening device when a frontal collision of the vehicle occurs. [0004] Patent Document 1: Japanese Invention Patent Laid-Open Publication No. 2008-213546 [0005] Patent Document 2: Japanese Invention...
