Latest Patents
One of his latest patents is a gearbox for vehicle seats. This innovative gearbox is designed to inhibit rattling of its shaft while preventing an increase in sliding resistance at the shaft end. The gearbox is integral to the movable mechanism of a vehicle seat and includes a housing, a thrust bearing, and a cap. The housing accommodates a shaft, a gear, and a rotary bearing, featuring a female screw portion. The thrust bearing has a force applied portion that contacts the end of the shaft, a male screw portion that engages with the female screw portion, and an engaged portion that interposes the male screw portion between itself and the force applied portion in the axial direction of the shaft. The cap includes an engaging portion that connects with the engaged portion of the thrust bearing, along with a removal stopper that restricts the thrust bearing's removal from the housing.
Another significant patent by Tatewaki is a gearbox that consists of a first helical gear and a second helical gear that engages with the first. The casing includes a first member positioned near the first helical gear and a second member near the second helical gear. A screw fastens the first member to the second member and is located closer to the first helical gear than the engagement position between the two gears. Additionally, a clip is positioned closer to the second helical gear than the engagement position, formed as a closed curve that encloses the ends of both members.
