Description
- This application claims priority to U.S. Provisional Application Serial No. 60/466,933, filed Apr. 30, 2003 and U.S. Provisional Application Serial No. 60/517,581, filed Nov. 5, 2003.
- This invention relates to vehicle occupant weight sensing and classification and more particularly to occupant weight sensing and classification in an adjustable seat.
- An automotive car seat typically includes a seat base and a seat back and is mounted to an automobile chassis by a support arrangement. In an adjustable automotive car seat, the support arrangement is usually movable by means of electric motors and connected to the seat by four pivoted links. One example is shown in WO 02/074575.
- Generally, it is sometimes desirable to determine the weight, classification and position of an occupant of a seat in a vehicle passenger compartment. For example, based upon the weight of the occupant and the position of the occupant on the seat, an active safety restraint system may determine whether or not to deploy or may determine the amount of force with which to deploy. One way of achieving this is by using a plurality of load cells mounted beneath the vehicle seat.
- Prior art implementations of weight sensors in adjustable vehicle seats have had some drawbacks. For example, implementing weight sensors in adjustable vehicle seats has often required a complete redesign of the vehicle seat structure in order to accommodate the sensors. Also, many of the prior art designs leave the sensors vulnerable to severe overloads in the event of a collision, such that the sensors would have to be replaced at additional cost.
- The use of weight sensors below the vehicle seat has also been complicated by the over-cinching of the seat belt. If the seat belt is cinched tightly on a child seat, this increases the weight reading on the weight sensors. The increase in weight on the sensors by the cinched seat belt could incorrectly lead to the determination that an adult is in the vehicle seat. To overcome this problem, some systems incorporate a belt load sensor, which measures the tension in the seat belt so that it can be subtracted from the weight sensors reading to determine the occupant weight. However, the belt load sensor increases the overall cost of the system.
- The present invention provides an improved adjustable seat with weight sensors. The invention could be applied to both a manual adjustable seat and a power adjustable seat. Therefore, unless otherwise specified, the term “adjustable” is intended to include manual and power adjustable seats.
- The present invention provides an improved vehicle seat subframe assembly that can be installed in existing adjustable vehicle seat designs without substantial modification. The subframe assembly includes a subframe to which are attached a plurality of seat height adjuster links and a plurality of weight sensors. The subframe assembly is adapted to be mounted between the vehicle seat and a seat slide assembly. In one embodiment, the seat height adjuster links are connected to the seat slide assembly and the weight sensors contact the vehicle seat. In another embodiment, the seat height adjuster links are connected to the vehicle seat and the weight sensors contact the seat slide assembly. Overload bolts provide gaps that protect the weight sensors from being overloaded in the event of a collision.
- In either embodiment, the seat occupant weight sensors are safe when abnormal force acts on the seat. The gap between the rigid frame and the seat base protects sensors from being overloaded. Within a predetermined range the seat occupant weight sensors experience restricted seat displacement relative to the support arrangement. This is especially true for power adjustable seats. Use of the vehicle seat subframe of the present invention in an existing adjustable seat design causes little or no increase in overall seat height.
- Other advantages of the present invention can be understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
- FIG. 1 is a schematic representation of a vehicle seat assembly according to a first embodiment of the present invention.
- FIG. 2 is a perspective view of the seat subframe assembly and seat slide assembly from FIG. 1.
- FIG. 3 is an enlarged bottom perspective view of one front corner the assembly of FIG. 2.
- FIG. 4 is an enlarged bottom perspective view of one rear corner of the assembly of FIG. 2.
- FIG. 5 is an enlarged top perspective view of the rear corner of the assembly of FIG. 4.
- FIG. 6 is a sectional view along lines6-6 of FIG. 5.
- FIG. 7 is a schematic view of a vehicle seat assembly according to a second embodiment of the present invention.
- A
vehicle seat assembly 10 according to a first embodiment is shown schematically in FIG. 1. Aseat subframe assembly 12 is mounted below avehicle seat base 14 and seat back 16 and above lower tracks 20 (one shown). The schematic of FIG. 1 shows the components stacked on upon another for clarity, although it should be recognized that in reality there is substantial overlap, such that the overall height of thevehicle seat assembly 10 is not increased. - The
seat subframe assembly 12 includes asubframe 22 connected to lower ends of a plurality of seatheight adjustment links 24. Theseat subframe assembly 12 further includes a plurality ofweight sensors 26 mounted to thesubframe 22. Theweight sensors 26 measure weight between thesubframe 22 and an upperseat slide assembly 28. - A perspective view of the seat subframe assembly12 (without the seat height adjustment links 24) and upper
seat slide assembly 28 is shown in FIG. 2. The plurality ofweight sensors 26 are mounted inmounting sleeves 30 formed at the corners of thesubframe 22. A plurality ofmounting tabs 34 are formed in thesubframe 22 for attaching to the lower ends of the seat height adjustment links 24 (FIG. 1). - The upper
seat slide assembly 28 includes a pair ofseat track slides 40 connected at the front by afront cross member 42 and at the rear by arear cross member 46. Therear cross member 46 is attached to the rear of theseat slides 40 byrear thrust brackets 48.Shoulder bolts 54 attach therear thrust brackets 48 and seatbelt attachment brackets 50 to theseat slides 40. - FIG. 3 is an enlarged bottom perspective view of one front corner of seat subframe assembly of FIG. 2. As can be seen in FIG. 3, each of the
front weight sensors 26 is attached to a mounting hole 60 in thefront cross member 42. Thefront weight sensors 26 measure weight between thesubframe 22 and thefront cross member 42. - FIG. 4 is an enlarged bottom perspective view of one rear corner of the seat subframe assembly of FIG. 2. As can be seen in FIG. 4, each
rear weight sensor 26 is attached to amounting hole 64 in one of therear thrust bracket 48. Therear weight sensors 26 measure weight between thesubframe 22 and therear thrust brackets 48. - FIG. 5 is an enlarged top perspective view of the rear corner of the seat subframe assembly of FIG. 4. FIG. 6 is a sectional view along lines6-6 of FIG. 5. Referring to FIGS. 5 and 6, the
subframe 22 includes two weight sensor brackets 66 (one shown) at its rear end protruding beyond the seat. Themounting sleeves 30 are each on aweight sensor bracket 66. This provides seat belt attachment points mechanically linked to the suspended part of thesubframe 22. There is a clearance of approximately 3 mm between the bottom face of theweight sensor bracket 66 and the top face of theseat track slide 40. Such a kinematical arrangement of the seat belt attachment points allows elimination of seat belt tension sensors. - The two
shoulder bolts 54 are firmly attached to the rear end of eachseat track slide 40. Theshoulder bolts 54 go throughholes 68, 69 in the seatbelt attachment bracket 50 and theweight sensor bracket 66. Theholes 68, 69 in the seatbelt attachment bracket 50 andweight sensor bracket 66 are slightly larger than the diameter of theshoulder bolts 54 to provide a guaranteed clearance relative to the shoulder of theshoulder bolt 54. There is also a clearance between the head of theshoulder bolt 54 and the upper surface of the seatbelt attachment bracket 50 and between theshoulder bolt 54 and the upper surface of theweight sensor bracket 66. Both clearances are important in order to avoid measured force offload in operation. The clearances offload force from theweight sensors 26 in the event of a crash or other unusually high force that would otherwise damage thesensors 26. - FIG. 7 is a schematic view of a
vehicle seat assembly 110 according to a second embodiment of the present invention. Thevehicle seat assembly 110 includes aseat subframe assembly 112 again including asubframe 122 to which are mounted a plurality ofweight sensors 126 and the upper ends of a plurality of seat height adjustment links 124. In this embodiment, theweight sensors 126 engage theseat base 114, while the seat height adjustment links 124 connect to the upper seat slide assembly 128. - In accordance with the provisions of the patent statutes and jurisprudence, exemplary configurations described above are considered to represent a preferred embodiment of the invention. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
