For reaching above-mentioned purpose, the utility model provides a kind of sit-ups body-building assisting device, the auxiliary member having cushion, back cushion and be connected between cushion and back cushion, and cushion and back cushion are vertical configuration, wherein:
This auxiliary member is with made by the elastic material of tabular, and this auxiliary member has the elastic portion of arcuation, and elastic portion both sides are extended with connecting portion, and connecting portion is connected to cushion and back cushion, and back cushion is pivoted with back against wheel in the surface of the side away from cushion.
Described sit-ups body-building assisting device, wherein: the elastic portion of this auxiliary member is bent with the first kink increasing elastic force.
Described sit-ups body-building assisting device, wherein: the quantity of this first kink is multiple.
Described sit-ups body-building assisting device, wherein: the connecting portion of this auxiliary member is bent with the second kink increasing elastic force.
Described sit-ups body-building assisting device, wherein: the elastic portion of this auxiliary member is bent with multiple the first kink in order to increase elastic force, and elastic portion is provided with waist against wheel, waist is provided with butting section against wheel, both sides, butting section are extended with fulcrum, and each fulcrum is between two of auxiliary member corresponding the first kinks.
Described sit-ups body-building assisting device, wherein: this cushion surface is provided with cushion air-vent.
Described sit-ups body-building assisting device, wherein: this back cushion surface is provided with back cushion air-vent.
The beneficial effects of the utility model are: utilize and have flexible auxiliary member, when allowing user change into sitting posture by back floating position, provide the auxiliary force that user stands up, exert a force to avoid user and excessively cause somatic damage, and can reduce costs, increase user's purchase intention.
