The utility model is intended to for Problems existing in existing product technology, there is provided a kind of angle can opening thigh and upper body in uncorrelated mode that seated person is drawn oneself up naturally and form tall and straight sitting posture, the sitting posture distortion that simultaneously can prevent the random rotation of seat and slip from causing and dispersion attention, and set clear and definite adjustment for individual difference and instruct sign, even if the juvenile keeping correct sitting posture still to feel comfortably cool for a long time is in addition good for ridge chair.
Juvenile of the present utility model is good for ridge chair and comprises main backstop, cushion, knee hassock, knee hassock bracing frame, lumbar support bar, base, cushion is fixed on main backstop to become to lean forward shape, and cushion surface leans forward and is greater than 5 degree with the angle in horizontal positioned face and is less than 30 degree, and knee hassock is fixed by knee hassock bracing frame and main backstop, the angle that the face of knee hassock and the face of cushion are formed is greater than 100 degree and is less than 145 degree, and the angle that seated person can open thigh and upper body naturally makes health form tall and straight sitting posture.
Described main backstop is the twisted plate of a global formation, width is not more than 200mm, thickness is more than or equal to 15mm and is less than or equal to 45mm, main backstop twisted plate only has one end to be fixed on base, and upper end is connected and fixed lumbar support bar, middle and upper part fixed installation cushion, middle and lower part fixed installation knee hassock, bottom is fixedly mounted on base, and base bottom has plastic cement pad, and during use, chair can not arbitrarily rotate and slide.
The fixing contact portion in described main backstop and cushion bottom surface is flat face, and flat face length is greater than 20mm and is less than 400mm, and cushion is fixed on shape that main backstop becomes to lean forward, and cushion surface leans forward and is greater than 5 degree with the angle in horizontal positioned face and is less than 30 degree.
There is at least one elongated hole described main backstop and knee hassock bracing frame junction, the length in hole is greater than 5mm and is less than or equal to 150mm, knee hassock bracing frame realizes position adjustments by being fitted in main backstop moves along main backstop curved surface direction, and the distance of removable adjustment is for being no more than 150mm.
The position adjustments of described knee hassock bracing frame, according to the length of human thigh, that posts setting adjustment position on adjustment elongated hole side instructs label.
Described knee hassock is arranged on knee hassock bracing frame, and the angle that its subject plane and main backstop are formed is greater than 75 degree and is less than or equal to 90 degree.
Described lumbar support bar, for length is less than 600mm, diameter is greater than the round bar that 30mm is less than 80mm, is directly fixed on the upside terminal part of main backstop, plays supplemental support effect to waist.
Juvenile of the present utility model is good for ridge chair, during use, lap extends forward along cushion surface direction, get down on both kneels on knee hassock, thigh and upper body open angle are greater than 100 degree, leaning forward of thigh femur is utilized indirectly to promote hipbone, it is straight and upright that hipbone promotes again lumbar vertebrae indirectly, and health goes into tall and straight sitting posture naturally, effectively can prevent the generation of spondylodynia.
Can not arbitrarily rotate because juvenile of the present utility model is good for ridge chair and slide, so the dispersion of can effectively avoid user to rock sitting posture distortion that health causes and notice, be conducive to for longer periods keeping correct sitting posture.
The lumbar support bar round bar being fixed on the upside terminal part of main backstop plays supplemental support to waist.
Described juvenile of the present utility model is good for teenager and the children that ridge chair can be applicable to height 100cm-170cm, knee hassock position can according to user's thigh length (under sitting posture, measured value during thigh horizontal positioned after knee front end to buttocks), carry out corresponding setting.
The inner core of knee hassock and cushion adopts soft material, effective partial pressure, and improve comfort level, the delay fatigue phase is beneficial to user and keeps correct sitting posture for a long time.
