可曲性椅背200具有二側框部210及位於該二側框部之間的一椅背本體220。二側框部210的底端分別接續於椅座100之背板110的二側。椅背本體220具有位於上部的一背靠部221與位於下部且向前突出的一護腰部222，其中，背靠部221與二側框部210各以一連接部223相接續，而護腰部222則與二側框部210相分離而具有一間隙224。護腰部222的背面設有與直向滑槽111相對應數量的一凸柱225，其可滑動地容置於直向滑槽111。直向滑槽111可以限制凸柱225的滑動行程及限制護腰部222的突出程度。 The flexible seat back 200 has two side frame portions 210 and a seat back body 220 between the two side frame portions. The bottom ends of the two side frame portions 210 are respectively connected to the two sides of the back plate 110 of the seat 100. The backrest body 220 has a backrest portion 221 at the upper portion and a waist portion 222 located at the lower portion and protruding forwardly. The backrest portion 221 and the two side frame portions 210 are each connected by a connecting portion 223, and the waist portion is connected. 222 is separated from the two side frame portions 210 and has a gap 224. The back of the waist guard 222 is provided with a number of protrusions 225 corresponding to the straight chutes 111, which are slidably received in the straight chutes 111. The straight chute 111 can limit the sliding stroke of the stud 225 and limit the degree of protrusion of the waist guard 222.

椅背本體220之背靠部221及護腰部222開設有多個透氣孔226，使得乘坐者的背部具有透氣效果。 The backrest portion 221 and the waist guard portion 222 of the back cover body 220 are provided with a plurality of venting holes 226, so that the back of the occupant has a breathable effect.
請一併參閱第6圖，當乘坐者300乘坐於椅座100，並將背部310倚靠於可曲性椅背200時，其人體背部310的倚靠重量會迫使可曲性椅背200的背靠部221及二側框部210後傾，且因為可曲性椅背200的護腰部222與二側框部210之間具有間隙224，因此護腰部222並不會隨著背靠部221同體後傾，而係背靠部221的後傾動作會相對的使得護腰部222以連接部223為軸而向前突隆，而且依乘坐者不同程度的倚靠仰度，護腰部222會產生不同程度之相對應的向前突隆。 Referring to FIG. 6 together, when the occupant 300 rides on the seat 100 and leans the back 310 against the flexible back 200, the weight of the back of the human body 310 forces the back of the flexible back 200 The portion 221 and the two side frame portions 210 are inclined backward, and because the waist portion 222 of the flexible seat back 200 and the two side frame portions 210 have a gap 224, the waist guard portion 222 does not follow the backrest portion 221 The back tilting action of the backrest portion 221 causes the waist guard portion 222 to swell forward with the connecting portion 223 as an axis, and the waist portion 222 is different depending on the occupant's varying degree of leaning. The corresponding forward spurs.
再詳細言之，在乘坐者300乘坐於椅座100，並將人體背部310倚靠於可曲性椅背200時，當乘坐者300人體背部310愈後仰時，乘坐者的腰部320係相對的愈向前，而此時人體背部310的倚靠重量會促使可曲性椅背200的護腰部222愈向前突隆(同時，護腰部222背面所設的凸柱225係沿著直向滑槽111向上滑動)，因此，乘坐者300此時向前的腰部320可以受到相對應程度向前突隆的護腰部222所有效的支撐及依靠，減低人體腰部的負擔；當乘坐者300人體背部310向前傾時，乘坐者的腰部320係相對的向後，而此時人體背部310會減輕對背靠部221的施壓，相對使得護壓部222向後回收而減低護腰部222向前突隆的程度(同時，護腰部222背面所設的凸柱225係沿著直向滑槽111向下滑動)，因此，乘坐者300此時向後的腰部320可以受到相對應突隆程度的護腰部222所有效的支撐及依靠，減低人體腰部的負擔。 In more detail, when the occupant 300 rides on the seat 100 and leans the human back 310 against the flexible back 200, when the occupant 300 is more reclined, the occupant's waist 320 is opposite. The more forward, while the weight of the back 310 of the human body causes the waist portion 222 of the flexible seat back 200 to swell forward (at the same time, the boss 225 provided on the back of the waist portion 222 is along the straight chute) 111 slides up), therefore, the occupant 300 at this time the forward waist 320 can be effectively supported and relied on by the corresponding degree of the front waist 222, reducing the burden on the human waist; when the occupant 300 human back 310 When leaning forward, the waist 320 of the occupant is relatively backward, and at this time, the back 310 of the human body relieves the pressure on the backrest portion 221, and the pressure-retaining portion 222 is recovered backward to reduce the forward bulging of the waist portion 222. The degree (at the same time, the boss 225 provided on the back of the waist guard 222 slides down the straight chute 111), so that the occupant 300 at this time can be subjected to the waist portion 222 of the corresponding bulging degree. Effective support and dependence to reduce the burden on the human waist .
依據本發明一實施方式之椅背支撐調節結構，可依乘坐者不同的乘坐姿態，隨時相對應的自動調節椅背護腰部的前後突隆程度，使得乘坐者的腰部隨時都能獲得有效的支撐及依靠，減低人體腰部的負擔，而使其乘坐舒適。 According to an embodiment of the present invention, the seat back support adjustment structure can automatically adjust the front and rear swell of the back of the seat back according to the different postures of the occupants, so that the occupant's waist can be effectively supported at any time. And rely on, reduce the burden on the human waist, and make it comfortable to ride.
