Embodiment Construction

[0035] Will refer to figure 1 The schematic diagram illustrates the seat adjustment mechanism 100 according to the embodiment. The first seat member 101 and the second seat member 102 are connected to each other by a hinge shaft 103 (connection point H) so that the end of each of the first seat member 101 and the second seat member 102 can be figure 1 Relatively rotate in the direction indicated by the arrow "m" shown in. In addition, the seat adjustment mechanism 100 is provided between the first seat member 101 and the second seat member 102 and includes the first link member 110 and the second link member 120 and the drive member 130 at the same time. The driving member 130 includes a driving device 131 and is driven by the driving device 131 and is figure 1 The telescopic device 132 linearly reciprocates in the direction indicated by the arrow "n" shown in. The seat adjustment mechanism 100 is configured to linearly reciprocate the telescopic device 132 driven by the dri...

Abstract

The invention discloses a seat apparatus and a seat adjustment mechanism for the same. The seat adjustment mechanism (100), which adjusts an angle formed between first and second seat members rotatably connected to each other, includes a first link member (110) adapted to be connected to the first seat member (101) and including a first end rotatably supported by the first seat member (101), a second link member (120) adapted to be rotatably connected to the second seat member (102) and including a first end rotatably supported by the second seat member (102) and a second end rotatably connected to the first link member (110), a drive device (131), and an extending and retracting device (132) driven by the drive device (131) and extending and retracting linearly, wherein one of the drive device (131) and the extending and retracting device (132) is rotatably connected to a second end of the first link member (110) and the other of the drive device (131) and the extending and retracting device (132) is rotatably connected to the second seat member (102).

Description

Technical field [0001] The present disclosure relates to a seat device and a seat adjustment mechanism for the seat device, the seat adjustment mechanism tilts the upper back portion of the double-folding backrest in the longitudinal direction of the vehicle. Background technique [0002] JP2008-254645A (hereinafter referred to as "Reference 1", see paragraphs 0006, 0017 and 0018 and Figure 4 The double-folding backrest of a known vehicle seat device disclosed in) is divided into an upper back part supporting the shoulder blades of the occupant and a lower back part supporting the waist of the occupant. The upper back portion includes an upper frame each serving as a first seat member, and the lower back portion includes a lower frame each serving as a second seat member. Each upper frame of the upper backrest part and each lower frame of the lower backrest part are rotatably connected to each other on their respective sides by hinge shafts. The backrest angle adjustment mechani...
