  • Patent number: 5122105
    Abstract: A seat (12) for an exercise apparatus is disclosed. The seat (12) includes a seat member (40), a back member (60), and a pair of wing members (67) that form an integral part of the back member (60). The pair of wing members (67) define a substantially vertical gap (68) therebetween. The back member (60) supports a rower's back when the rower is sitting on the seat member (40). The back member (60), including an pair of wing members (67), is designed to deflect backward during the drive portion of the rowing motion. The pair of wing members (67) are designed to additionally deflect in such a manner that they cup the rower's back during the drive portion of the rowing motion. A supportive insert (80), which extends into the seat member (40) and the back member (60), affects the flexibility of the back member (60) and the pair of wing members (67). The seat (12), including its foam exterior (90), is configured to maximize the comfort of the rower.
