With further reference to Figures 1 and 2, the seat assembly 10 can be used in any vehicle 40, such as a car, truck, van, etc. It is also considered that the concept set forth in this disclosure can be used in a front position as well as a rear position of the vehicle 40. As illustrated, the seat assembly 10 includes a seat base 42 positioned on rail slides 44 to allow forward and backward movement of the seat assembly 10 relative to the vehicle 40. The seat 12 is operatively connected to the seat base 42 and can be moved relative to it, as detailed below. A seat surface of the seat 12 is generally configured to support an occupant.Furthermore, the backrest 13 of the seat assembly 10 includes a frame 47 that supports a lower lumbar region 48 and an upper thoracic region 49, as well as a headrest 45. Each of the components of the backrest 13 can be configured for adjustability in order to adequately support the weight of different occupants in the vehicle 40. Now, with reference to Figures 3-5, the seat assembly 10 includes a first and second thigh support 50, 52, which can be moved independently and are supported on a seat support 53. The seat support 53 includes side walls 51 with rear vertical support flanges 55. The seat support 53 also includes an arcuate back wall 57, which is configured to rest against an upper section of the front cross tube 22. Each of the first and second independently movable thigh supports 50, 52 is arranged next to a side cushion support 54. The side cushion supports 54 include attachment features 56 for receiving a cushion assembly 60. A suspension assembly 62 is arranged below the cushion assembly 60 between the first and second independently movable thigh supports 50, 52 and the arcuate back wall 57. The rear cross member receives the ends of the suspension assembly 62.The suspension assembly 62 comprises a first and second elongated spring element 66, 68, each containing a central section 70 operatively connected to a restraint device 72 near each of the independently movable thigh supports 50, 52 of the first and second elongated spring elements. Each of the first and second elongated spring elements 66, 68 includes a plurality of fastening elements 76 configured to attach various components beneath the seat assembly 10. Furthermore, a central section of the seat 12 includes a receiving ring 78 that defines an opening 80 for receiving a climate control element duct or blower. With reference again to Fig. 4, the seat assembly 10 is illustrated, with the first and second independently movable thigh supports 50, 52 removed. The first and second elongated spring elements 66, 68 are illustrated and configured to support the buttocks of an occupant. The front assembly bracket 14 is operatively connected to the assembly 10 and is located above the front cross tube 22, below the first and second independently movable thigh supports 50, 52. The front assembly bracket 14 is coupled to a front section of the seat support 53. As shown in Figures 6-9, the front assembly bracket 14 includes a body section 90 that generally extends laterally and is configured for attachment to rear pivot points 92 on the seat 12. A rear section of the front assembly bracket 14 includes a rear vertical support wall 94, which adds rigidity to the front assembly bracket 14. The front assembly bracket 14 also includes side walls 95. The front assembly bracket 14 includes a receiving opening 96 configured for secure engagement with a fastener 98 of the rear restraint element 18. The front assembly mount 14 also includes receiving openings 101 configured to receive forward-extending hook features 102. In the illustrated embodiment, these are a first and second forward-extending hook feature 102. However, it is understood that more or fewer forward-extending hook features 102 than illustrated herein may be present. The forward-extending hook features 102 are configured to engage the front cross tube 22 to allow the seat 12 to rotate into a lower position until the seat 12 is securely seated against the seat frame 47. The front assembly mount 14 also includes projections extending upward from the body section 90, configured to securely restrain the stops 106, which prevent the first and second independently movable thigh supports 50, 52 from over-rotating upward.The forward-extending hook features 102 each define a receiving opening 100 to accommodate the front cross tube 22. Furthermore, each of the forward-extending hook features 102 includes a polymer sleeve to minimize noise, rattle, and squeak. The forward-extending hook features 102 also include a plurality of reinforcing ribs 110 configured to engage an upper section of the front cross tube 22. It should be noted that the plurality of reinforcing ribs 110 is defined in a section of the sleeve located within the receiving opening 100 of the forward-extending hook features 102. However, it is considered that the plurality of reinforcing ribs 110 could be formed in the front assembly mount 14 or as part of the forward-extending hook features 102. Now, with reference to Figures 9-12, the rear retention element 18 and the front retention element 26 are illustrated. The rear retention element 18 defines a receiving opening 20 configured to engage the front cross tube 22 in a similar manner to the forward-extending hook features 102. However, the rear retention element 18 is configured to press against the front cross tube 22 and maintain a secure engagement with it after the seat 12 is installed. This is achieved by the rear retention element 18 engaging with the front retention element 26. The rear retaining element 18 comprises an upper mounting body 120 with a mounting opening 122 located therein, and a lower arcuate section 124 designed to accommodate the front transverse tube 22. The polymer sleeve 24 extends over the arcuate section 124. A front end of the arcuate section 124 includes a lower wall 126 having a mounting opening 127 designed to receive a fastener. The front retaining element 26 is located in front of the rear retaining element 18 and can be actuated between an open and a closed position. The front retaining element 26 includes a polymer sleeve 130 near an arcuate section 132 thereof.A lower wall 134 extends downward from the arcuate section 132 and includes a mounting opening 136, which is generally aligned with the mounting opening 127 of the lower wall 126 of the rear retaining element 18. An engagement head 140 is positioned above the arcuate section 132 and is configured for linear forward and backward translation within an opening 142 defined in a recess 143 of the front assembly holder 14. The engagement head 140, together with the arcuate section 132, defines receiving slots 144 that engage with the front assembly holder 14. When correctly engaged, the engagement head 140 extends through the opening 142, and the arcuate section 132 extends beneath the assembly holder 14.Thus, the front retaining element 26 can be moved forwards and backwards and can also be pivoted to come into contact with the rear retaining element 18 in order to hold back the front cross tube 22 during assembly. As illustrated in Fig. 9, the front retaining element 26 is in a rear position and is configured to engage with the rear retaining element 18. During forward movement and downward rotation of the front retaining element 26, the lower wall 126 of the front retaining element 26 and the lower wall 134 of the rear retaining element 18 abut each other, so that the mounting openings 136, 127 are each aligned and configured to receive a fastener. In the illustrated embodiment of Figs. 10 and 11, the front transverse tube 22 is not shown. However, the person skilled in the art understands that the front transverse tube 22 extends through the receiving opening 20 defined between the rear retaining element 18 and the front retaining element 26. Now, with reference to Figures 13-15, the seat assembly 10 also uses the rear assembly bracket 28 to securely engage the seat 12 with the seat assembly 10. As disclosed above, the rear assembly bracket 28 includes the tab end 30, which is operatively connected to the seat 12. In particular, the tab end 30 engages the rear wall 57 of the seat support 53. The tab end 30 extends through a slot 150 and can be adjusted within the slot 150. The rear assembly bracket 28 also includes the rounded body 32, which is configured to engage the rear cross tube 34. The fastening end 36 of the rear assembly bracket 28 is configured to securely engage an engagement tab 152 extending from the rear wall 57 of the seat 12.When in use, the tab end 30 extends through the slot 150 in the rear wall 57 of the seat support 53 of the seat 12 and rotates within the slot 150 until the rounded body 32 of the rear assembly bracket 28 rests against the rear cross tube 34. At full rotation, the fastening end 36 rests against the engagement tab 152, which extends from the rear wall 57 of the seat support 53, until a fastener 154 can be extended through a fastening opening 156 of the engagement tab 152 and a fastening opening 158 of the fastening end 36 (Fig. 15). Once securely engaged, the seat support 53, and consequently the seat 12, is ready for use. During the manufacturing process, the seat support 53 and the seat 12 are prepared for engagement with the seat frame 47. The forward-extending hook features 102 are positioned on the front cross tube 22. The seat 12 is then rotated downwards into position until a rear engagement channel of the seat support 53 engages the rear cross tube 34. Once engaged, the rear assembly holder 28 is rotated into position until the fastening end 36 engages a tab on the seat support 53. A mechanical fastener is then extended through the fastening end 36 and the tab. At a front end of the seat 12, the front retaining element 26 is rotated downwards into position so that the lower wall 134 of the front retaining element 26 is in butt contact with the lower wall 126 of the rear retaining element 18. A mechanical fastener is then positioned through the mounting opening 127 of the rear retaining element 18 and through the mounting opening 136 of the front retaining element 26. The seat support 53, and consequently the seat 12, is now attached to the seat assembly 10 and ready for use. The design provides a quick and secure method for attaching a seat support and seat to a seat assembly during the manufacturing process. Minimal fasteners are required, and the assembly can be erected in a minimal amount of time.
