AI Technical Summary
Technical Problem
Existing seat frames in motor vehicles are not sufficiently flexible at low speeds to absorb energy from rear impacts without transferring it to the occupant, potentially causing injuries like whiplash.
Method used
The seat frame incorporates a gusset with two adjacent elongated openings, one with a bent shape and one with a triangular shape, allowing controlled deformation during impacts to dissipate energy without transmitting it to the occupant.
Benefits of technology
The frame effectively absorbs energy during low-speed impacts by deforming plastically, reducing the risk of injuries by preventing energy transmission to the occupant, while maintaining performance in higher-speed collisions.

Abstract
The invention relates to a seat frame for a motor vehicle comprising a seat structure (5) and a backrest structure (8), the backrest structure comprising at least one gusset (50) designed to fix said backrest structure to the rear of the seat structure, said gusset comprising, on its rear edge, a first opening (53). According to the invention, said gusset further comprises at least one second opening (54) adjacent to the first opening, said first opening and said second opening having elongated shapes respectively along substantially parallel first (A1) and second (A2) directions.
