In Fig. 1-2 B illustrated embodiment, reinforcing member 32 is connected to the back side (that is: passenger's reverse side on the back of seat) of seat back system 20.In addition, member as shown in the figure can also be set on the seat back system or a plurality of positions of its in-to-in.One or more strenthening members can be arranged on the back side of seat back panel, one or morely can be arranged on the front, or are integrated in the inside of seat back panel.One or more strenthening members can also be along the exterior boundary setting of seat back panel.Also can consider these strenthening members horizontal along seat back panel, vertically, level, vertical, tilt or their array configuration setting.
In this embodiment, reinforcing member 32 is connected in the integrated strenthening member of seat back system 20.And reinforcing member 32 also can be arranged in the space (for example die cavity or through hole) or the plane on.
According to the present invention, seat back panel all can comprise one or more projections in the strenthening member, to assist the strenthening member setting and to be connected on the seat back panel.Preferably, projection can be inserted in the corresponding space (for example die cavity or through hole), and it can be a reinforcing member, the form that seat back panel or both have concurrently.Shown in Figure 3 is a plurality of projections 70 of stretching out from timber 60, and these projections 70 can be inserted the through hole 72 on the reinforcing member 32.
During concrete the application, should be according to following some or all criterions, the design of each strenthening member of optimization and position, or its making pattern in back of seat.For each application, can enjoy with those skilled in the art: use this concrete strenthening member can help to reduce because self-propelled vehicle is fast quickens or slow down soon or bending effect that seat rear passenger or goods (for example roof-mounted center safety strap, the pinnacle of roof-mounted child safety seat and luggage) are caused.For example, one preferred embodiment in, ruggedized construction of selecting for use usually or pattern are that the strenthening member that will have higher bending moment vertically is set to coilable curved ramp place.
Seat back system provided by the invention may be used on front stall, back seat, and folded seat etc. are located.Also can consider to be processed into and be applicable to the child safety seat tether, the seat back system of postmedian safety strap.This system also should meet the standard (for example strength criterion) that pre-establishes.Patent USP60/414, in 040 to seat, tether, safety strap and standard have been carried out detailed discussion.
Though the present invention has only related to automotive vehicle seat system, skilled worker skilled worker will recognize that this system also can be applicable to other seat, as aircraft and bus seat or auditorium and stadium seat.
Below only be to exemplified embodiment of the present invention.And those skilled in the art are by above said content, and accompanying drawing and claim can recognize, and are such just as defined by the following claims, under the prerequisite that does not depart from character of the present invention and scope, can carry out various changes, improve and distortion.Especially for described compound, assembling is installed, and the various functions that component etc. show under the situation of no certain illustrated, are not equal to term institute description scheme even if having the item of specific function, adopt this term description corresponding entry yet.In addition, the concrete feature that relates in embodiment can combine with the feature in other illustrated embodiment.
