Abstract
A toothed disc for the adjustment device of a reclining car seat and a method of manufacturing the same. A material strip is placed onto a precision blanking machine. The material strip is stamped so that a portion of the material strip is displaced and formed in a first direction away from the material strip, the portion corresponding to at least one of addendum circle and a hub of a toothed gear. Next, the portion is formed in a direction towards the material strip, whereby the material corresponding to at least one of the addendum circle and a hub of the toothed gear is thickened. Then, a toothed gear is formed in the material strip. Lastly, the toothed gear is blanked from the material strip. All of the aforementioned steps are performed in sequence.
Claims6
A method of manufacturing toothed gears for a reclining car seat adjustment device, comprising the steps of:
- placing a material strip onto a precision blanking machine;
- stamping the material strip so that a portion of the material strip is displaced and formed in a first direction away from the material strip, said portion corresponding to at least one of addendum circle and a hub of a toothed gear;
- forming said portion in a direction towards the material strip, whereby the material corresponding to at least one of the addendum circle and a hub of the toothed gear is thickened;
- forming a toothed profile in the material strip;
- and
- blanking the toothed profile from the material strip to obtain the toothed gear, wherein said steps are performed in sequence.
A method as defined in claim 8, and further comprising an additional step of blanking at least one of a gear bore, a gear hub, a selecting hole and a material displacement strip from the material strip, said additional step being immediately subsequent to said placing step.
