Patent number: 10752138Abstract: Right and left brackets coupling a seat back frame and seat cushion frame together are configured to adjust an amount of deformation upon impact absorption. A vehicle seat frame includes a seat cushion frame, seat back frame, coupling bracket configured to couple a cushion side frame as a side frame of the seat cushion frame on one side of the vehicle seat frame and a seat back side frame as a side frame of the seat back frame on the one side, and coupling bracket configured to couple a cushion side frame as a side frame of the seat cushion frame on the other side and a seat back side frame as a side frame of the seat back frame on the other side. Deformability upon impact absorption is different between a weak portion provided at the coupling bracket and a weak portion provided at the coupling bracket.Type: GrantFiled: August 2, 2019Date of Patent: August 25, 2020Assignee: TS Tech Co., Ltd.Inventors: Hiroshi Baba, Takaya Kurisu, Yuki Hosokawa

Patent number: 9522617Abstract: Provided is a vehicle seat capable of efficiently absorbing impact energy generated upon a rear end collision in a manner such that the vehicle seat is stably deformed at a specific position with respect to a complex input load generated upon a rear end collision. A vehicle seat includes: frame side portions that are located at the right and left sides of a seat back frame and extend in the up to down direction; and frame extension portions that extend from the frame side portions toward the inside in the right and left direction. A connection portion that connects the frame side portions to the frame extension portions is provided with a deformation portion that is deformed when an impact load is applied thereto. The deformation portion is formed adjacent to other deformation portions having deformation characteristics different from that of the deformation portion.Type: GrantFiled: February 27, 2015Date of Patent: December 20, 2016Assignee: TS Tech Co., Ltd.Inventors: Yuichiro Seki, Takaya Kurisu, Kenichi Niitsuma
