Patent number: 11376994Abstract: Provided is a vehicle seat having a pitching function, which not only has an assist function for bringing a main frame to a seated position or a forward tilted position, but also prevents the increase in the width and the increase in the weight of the seat. The vehicle seat includes: a base frame; a main frame disposed on the base frame and having a back frame and a cushion frame; and a link mechanism that allows the main frame to swing to the seated position and the forward tilted position with respect to the base frame. A third rotating shaft of the link mechanism is provided with a torsion spring that urges the main frame to swing from the forward tilted position to the seated position.Type: GrantFiled: February 17, 2021Date of Patent: July 5, 2022Assignee: TACHI-S CO., LTD.Inventors: Masakazu Takeda, Keita Myochin, Naoki Toda

Patent number: 11332054Abstract: A vehicle seat (10) has a seat cushion (20) and a seat back (30), which are affixed to the body of a vehicle. The seat back (30) has: a first member (50) which is formed in a plate-like shape; and a second member (60) with a hat-shaped cross-section, which is configured so that a flange section (61) is in contact with one surface, in a thickness direction, of the first member (50). A center bead (52) is provided at the center portion of the first member (50). The center bead (52) is configured so that a longitudinal end of the center bead (52) and the second member (60) are overlapped in a plan view viewed in the thickness direction of the first member (50). As a result, the first member (50) of the seat back (30) is prevented from being deformed at the longitudinal end of the center bead (52).Type: GrantFiled: March 6, 2019Date of Patent: May 17, 2022Assignee: TACHI-S CO., LTD.Inventors: Masakazu Takeda, Mitsuru Tsukada, Keita Myochin, Tatsuya Iwasaki
