摘要： A motion chair includes a pair of side frames, each of which has a front leg, a rear leg and a side rail brace member interconnected therebetween. A seat is located between the side frames, and includes a pair of resilient spring-type seat frames. A seat mounting arrangement interconnects each seat frame with one of the side frames. The seat mounting arrangement includes a bracket-type mounting member to which the seat frame is secured. A seat support member is interconnected with the side rail member, and the seat mounting member is secured to the support member. In one form, the seat support member is a metal reinforcement member connected to the side rail member, which is preferably formed of a wood material. The reinforcement member distributes loads and stresses applied to the seat mounting member to and throughout the length of the brace member. In another form, the seat support member is a planar side member that spans across a joint between the leg and the side rail member. The side member is mounted to the front leg and is connected to the side rail member at a location spaced rearwardly from the joint, to isolate the joint from loads and stresses applied to the side member. The seat mounting arrangement allows use of a motion-type seat mounting mechanism in a conventional wood frame chair having a side rail member, in a manner which isolates the chair frame connections from the loads and stresses applied to the seat mounting member when a user is seated on the seat.
