Abstract: A damper is arranged between the seat backrest and the seat base. This damper applies a resistance to seat backrest movement, especially movement from the vertical position to the folded position. The damper includes a pin and profile mounted on the seat backrest and seat base respectively, or vice versa. The pin and profile slide against each other during movement of the seat backrest relative to the seat base. The shape, size, material, and/or the surface characteristics of the pin and profile determine the resistance to movement of the seat backrest. These parameters of the pin and profile can be varied, especially along different portions of the profile to apply the desired resistance at different angular positions of the seat backrest with respect to the seat base.

Abstract: A method of laser welding structures having different steel grades together. The method includes providing a first structure made from a first steel grade and composition and providing a second structure made from a second steel grade composition. The first structure is positioned adjacent the second structure to create a weld zone area wherein at least a portion of the first structure overlaps at least a portion of the second structure. A filler material is selected that has a composition that will create a weld joint between the first structure, the second structure and the filler material such that the weld joint has a predetermined microstructure. The filler material is positioned adjacent the weld zone area. A laser beam is directed at the weld zone area to create a weld joint between the first structure, the second structure and the filler material, wherein the weld joint has a predetermined microstructure.

Abstract: A seat back frame for use in a vehicle seat assembly including a first side member, a second side member, an upper cross member, and a lower cross member. The seat back frame also includes a load transfer member that transfers impact loads from a collision through the seat assembly.

Abstract: The present invention relates to a component {1, 2, 3, 4, 6) within the interior of a vehicle. Specifically, the present invention relates to a part of a seat-structure. The present invention further relates to a process to produce a component { 1, 2, 3, 4, 6) w{umlaut over (?)}thin the interior of a vehicle.

Abstract: A seat back structure includes a web extending about a central opening, and an inner flange extending about an inner perimeter of the web adjacent to the central opening. The seat back structure also includes an outer flange extending about an outer perimeter of the web. The inner flange, the outer flange and the web form a channel extending about the seat back structure, and the seat back structure is formed from a single piece of material.

Abstract: A one-piece back frame including an upper portion, a lower portion and a pair of vertical portions. The upper portion includes a first flange bent downwardly and a second flange bent upwardly to enclose the upper portion. The first and second flanges are brazed or welded to one another, which has the effect of strengthening the upper portion of the back frame and increasing its resistance to forces and moments during front or rear impact. Additionally, a pair of tubes extend through and are connected to upper portion. The tubes are designed for receiving a head restraint, but also serve the additional purpose of further strengthening the upper portion to increase its resistance to forces and moments during front or rear impacts.

Abstract: A seat bottom chassis includes a pair of brackets configured to support a seat back chassis, and a cushion pan extending between the pair of brackets. The seat bottom chassis is formed from a single piece of material.

Abstract: A seat track system for use in a vehicle seat assembly having a seat base frame. The seat track system includes a lower track assembly having a first lower track and a second lower track and an upper track assembly having a first upper track slidably disposed within the first lower track and a second upper track slidably disposed within the second lower track. The first upper track has a portion extending upwards that forms a first side member of the seat base frame and the second upper track has a portion extending upwards that forms a second side member of the seat base frame. The first upper track and the first side member are formed integrally to form a one-piece unitary member and the second upper track and the second side member are formed integrally to form a one-piece unitary member.

Abstract: A one-piece seat back frame for use in a vehicle seat assembly. The one-piece seat back frame includes a first side portion and a second side portion spaced apart from the first side portion, an upper cross portion and a lower cross portion. A lower cross bracket member is coupled to the seat back frame such that the lower cross bracket member at least partially overlaps the seat back frame lower cross portion forming a boxed section. A first recliner mechanism is coupled to the second end of the lower cross bracket member for a single-sided recliner system. A pivot bracket or a second recliner mechanism is coupled to the first end of the lower cross bracket member for a dual-sided recliner system.

Abstract: Disclosed is a back rest structure for vehicle seats and a method for manufacturing the same. The back rest structure has a back panel element and a seat back frame element fixed to each other, where at least one of the back panel element or the seat back frame element is provided of a thermoplastic composite material comprising a thermoplastic compound material and a reinforcement material, wherein with respect to the thermoplastic material the reinforcement material represents 50 wt-% or more than 50 wt-%.

Abstract: A seat structure may be installed in a seat assembly. The seat structure may comprise plurality of tube members forming a substantially closed structure. Some of the tube members have a substantially uniform cross-sectional area along a substantial portion of its respective longitudinal length. At least a first set of the tube members has at least one of a different dimensional property and a different material property from a second set of the tube members such that mechanical properties of each tube member is configured for stress requirements for a respective region that the respective tube member occupies. The plurality of tube members are joined such that the plurality of tube members are in fixed positions relative to each other.

Abstract: A front row vehicle seat including a back frame, a core and a trim cover. The back frame has a generally rectangular shape presenting an upper portion, a lower portion, a pair of vertical portions. The entire back frame is formed of one piece of metal, and thus, the portions are all integrally connected together. The core and trim cover are disposed about the back frame to provide a comfortable seating surface for an occupant of the vehicle.
