Abstract
Description
- A seat back frame assembly having an interference member configured to direct a passenger from a side member of the seat frame is provided.
- 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 further displace the occupant into a side member. Accordingly, it remains desirable to have a seat back frame assembly wherein the passenger is directed away from the side member.
- A seat back frame assembly and a seat assembly are provided. The seat back frame assembly includes a pair of side members. The side members are formed of a generally durable and rigid material. The side members are elongated and spaced apart from each other. A top member is spaced apart from a bottom member. Each of the top and bottom members interconnect each of the pair of side members defining the peripheral edge of the seat back frame assembly. The peripheral edge encloses a space which defines a back space.
- The seat back frame assembly includes an interference member. The interference member is disposed within the back space and is spaced apart from an inner surface of one of the pair of side members. The interference member is disposed above a midpoint of the side member. The interference member includes a sliding surface. The sliding surface is 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.
- The seat assembly includes a seat cushion having a seat frame and a seat back frame assembly pivotably mounted to the seat frame. The seat back frame assembly includes a pair of side members. Each of the pair of side members is spaced apart from the other. A top member is spaced apart from a bottom member. Each of the top and bottom members interconnect each of the pair of side members so as to define a peripheral edge of the seat back frame assembly. An interference member is disposed within the back space and is spaced apart from an inner surface of one of the pair of side members. The interference member is disposed above a midpoint of the side member so as to be positioned to engage the side of an occupant. The interference member includes a sliding surface. The sliding surface is 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.

With reference first toFIG. 7 , a top down view of theinterference member 122 is provided which shows the sliding surface 126. As is shown, the sliding surface 126 is angled obtusely with respect to theback space 120. The sliding surface 126 is spaced apart from and facing the side of the occupant. Upon experiencing a load directing the occupant towards theside member 112 b, the side of the occupant engages the sliding surface 126 of thebody 42 which directs the occupant forward and away fromside member 112 b, as indicated by the arrow shown inFIG. 6 . - With reference again to
FIGS. 1 and 2 , aseat assembly 200 is provided. Theseat assembly 200 includes aseat cushion 52. Theseat cushion 52 may be mounted to a seat frame 54 (shown in dashed lines). Theseat frame 54 may includeattachment structures 56 configured to pivotably attach theseat cushion 52 to seat backframe assembly 10. Theseat frame 54 may includeattachment structures 58 configured to attach theseat assembly 200 to the floor of an automotive vehicle (not shown). Alternatively, it should be appreciated that theseat frame 54 may be mounted to rails so as to enable theseat assembly 200 to slide back and forth. - The seat back
frame assembly 10 includes a pair ofside members side members frame assembly 10 further includes atop member 14 spaced apart from abottom member 16. Each of the top andbottom members side members peripheral edge 18 of the seat backframe assembly 10. Theperipheral edge 18 defines aback space 20. - The seat back
frame assembly 10 further includes aninterference member 22. Theinterference member 22 is disposed within theback space 20 and spaced apart from aninner surface 24 of theside member 12 b. Theinterference member 22 is positioned above a midpoint M of one of the pair ofside members - The
interference member 22 includes a slidingsurface 26. The slidingsurface 26 is angled obtusely with respect to theback space 20 so as to direct an occupant forward of theback space 20 and away from theside member 12 b when experiencing a side load. The seat backframe assembly 10 may further include aback support 34 disposed on theback space 20. Theback support 34 is fixed to theperipheral edge 18 of theback space 20. Theside members back space 20. A portion of theinterference member 22 is disposed along a plane generally parallel to the width of the pair ofside members interference members 22 each mounted to a respective one of the pair ofside members - With reference now to
FIGS. 1, 3, 4 and 5 , theinterference member 22 may be awire 36. Thewire 36 may be formed of a durable and rigid material such as steel. Thewire 36 includes a pair oflegs legs inner surface 24 of one of the pair ofside members elongated portions legs legs portion 36 e connects a distal end of the respective pair ofelongated portions - Each of the pair of
elongated portions pivot point 40. Thepivot point 40 defines aproximate portion 36 p of theelongated portions end portion 36 n of theelongated portions side members proximate portion 36 p of theinterference member 22 is disposed along a plane generally parallel to the width of the pair ofside members end portions 36 n of respectiveelongated portions surface 26. Thepivot point 40 may be formed by weakening the location of the respectiveelongated portions end portions 36 n of the respectiveelongated portions pivot point 40 may be formed by forming theelongated portions respective pivot point 40. - With reference now to
FIGS. 2, 6 and 7 theinterference member 122 is asolid body 42 having a sliding surface 126 disposed on thesolid body 42 opposite abase 44. Thebase 44 abuts against theside member 112 b. Theback wall 46 is generally orthogonal to thebase 44 and may be fixed to the seat backframe 110. A pair ofside walls 48 are disposed on opposite sides of thebase 44. Theback wall 46 extends between theside walls 48 and theside walls 48 are generally orthogonal to thebase 44. A top surface 50 is angled obtusely with respect to theback space 20 so as to form and define the sliding surface 126. Thebody 42 may be formed of a durable and rigid material such as steel or a polymer composite such as plastic or polyurethane. It should be appreciated that theinterference member 122 is also enclosed with the cushion material. - While particular embodiments have been illustrated and described herein, it should be understood that various other changes and modifications may be made without departing from the spirit and scope of the claimed subject matter. For instance, the drawings show only one interference member, however, the seat back frame assembly or seat assembly may include two interference members, each axially aligned with each other and each spaced apart from respective inner surfaces of
side members side members
