Benefits of technology

This patent describes a seat back frame assembly and seat assembly. The seat back frame assembly includes a pair of side members made of durable material, which are spaced apart and form the edges of the frame. An interference member is placed within the space between the side members and is angled to direct an occupant forward of the frame and away from the side member in case of a side load. The seat assembly includes a seat cushion with a pivotable seat back frame assembly. The interference member is positioned to engage the side of the occupant and directs them forward of the frame. The technical effect of this patent is to improve the safety and comfort of the seat assembly.

Problems solved by technology

However, as the seat back frame assembly is encompassed with foam, a side load may cause the passenger to compress the foam and further displace the occupant into a side member.

Embodiment Construction

[0014]The embodiments described herein generally relate to a seat back frame assembly 10 and a seat assembly 200 for use in an automotive vehicle (not shown). The seat back frame assembly 10 includes a pair of side members 12a, 12b. Each of the side members 12a, 12b is spaced apart from each other. A top member 14 is spaced apart from a bottom member 16. Side members 12a, 12b and top and bottom members 14, 16 are formed of a generally durable and rigid material such as steel. The top member 14 and bottom member 16 interconnect each of the side members 12a, 12b at a respective proximal and distal edges of the side members 12a, 12b so as to define a peripheral edge 18 of the seat back frame assembly 10. The peripheral edge 18 encloses a back space 20.

[0015]The seat back frame assembly 10 includes an interference member 22 disposed within the back space 20 and spaced apart from an inner surface 24 of side member 12b. The interference member 22 is positioned above a midpoint (“M”) of si...

Abstract

A seat back frame assembly and seat assembly are provided. The seat back frame assembly includes a pair of side members spaced apart from each other, a top member spaced apart from a bottom member, each of the top and bottom members interconnecting each of the pair of side members so as to define a peripheral edge, the peripheral edge enclosing a back space. An interference member is disposed within the back space and spaced apart from an inner surface of one of the pair of side members. The interference member disposed above a midpoint of the one of the pair of side members and includes a sliding surface angled obtusely with respect to the back space so as to direct an occupant forward of the back space and away from the side member when experiencing a side load.

Description

TECHNICAL FIELD[0001]A seat back frame assembly having an interference member configured to direct a passenger from a side member of the seat frame is provided.BACKGROUND OF THE INVENTION[0002]Seat back frame assemblies include a pair of side members spaced apart from each other. A top member extends between the top ends of a respective side member and a bottom member encloses the bottom ends of the side members. The seat back frame assembly is typically covered with a foam cushion, so as to form a seat back. The foam cushion is generally deformable so as to provide comfort to the user's back. The seat back frame assembly may be mounted to a seat frame having a seat cushion. In particular, in automotive use the seat back frame assembly is typically pivotably mounted to the seat frame so as to allow the user to adjust the angle of the seat back for comfort. However, as the seat back frame assembly is encompassed with foam, a side load may cause the passenger to compress the foam and ...
