The invention relates to a human engineering vehicle seat back frame, and also relates to a special welding tool thereof. The seat back frame comprises a left circular tube support and a right circular tube support which are respectively composed of an upper section, a lower section and a middle section. The inner sides of the upper parts of the upper sections of the left circular tube support and the right circular tube support are respectively welded with two ends of a headrest plate, the upper sections are welded with an upper backrest plate, the middle sections are welded with a middle backrest plate, and the lower sections are welded with a lower backrest plate. The tops of the upper sections are bent inwards and then are respectively welded with left and right upper armrest frames. The outer sides of the middles of the upper sections are welded with side armrest frames. The sides of the lower sections are welded with rotary armrest frames, and the bottoms of the lower sections are welded with backward inclination adjusting brackets of plug-in cards. After the frame is adopted, in a bumpy and impact dynamic environment, the stress is uniform, the strength can be ensured, and the abundant flexibility of the backrest can be always kept to be matched with the shape of the back of a human body, so that the comfort level is kept.
本发明涉及一种人体工程学车用座椅背架,同时还涉及其专用焊具。该座椅背架包括分别由上段、下段、中段构成左、右圆管支架;左、右圆管支架上段的上部内侧分别与头靠板的两端焊接,上段与上靠背板焊接,中段与中靠背板焊接,下段与下靠背板焊接;上段的顶部朝内弯曲后分别与左、右上扶手架焊接;上段的中部外侧与侧扶手架焊接;下段一侧与旋转扶手架焊接,下段的底部与插卡的后倾调节支架焊接。采用本发明后,在颠簸、冲击的动态环境中,受力均匀,可以保证强度,并且靠背的富裕柔性可始终保持与人体脊背形状吻合,从而保持舒适度。
