The present invention relates to a chair, and more particularly, to a chair with an adjustable seat pad unit.
Chairs play an important role in the modern world and people spend longer time sitting in the chairs everyday. For people work in offices, most of the time in a day is sitting in chairs. The design of a chair means a lot to the health of the users. The conventional chair is disclosed in
The present invention intends to provide a chair wherein the seat portion can be adjusted to meet the needs of different users.
The present invention relates to a chair and comprises a seat portion having two recesses defined in the top thereof and a fixing frame extends from the seat portion and is located close to the backrest. An adjustment device has a tube with two resilient members connected on two ends thereof. The two resilient members are received in the recesses. A seat pad unit is located on the seat portion and has a left pad and a right pad. A bearing unit is located at the underside of the seat pad unit and the fixing frame extends through the bearing unit. The seat pad unit is pivotable relative to the seat portion.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
An adjustment device 2 has the adjustment unit 21 and a fixing unit 22, wherein the adjustment unit 21 has a tube 212 with two resilient members 211 connected on two ends thereof. The fixing unit 22 extends from the adjustment unit 21 and has protrusions 221 extending therefrom which are fixed to the seat portion 1 by connecting the multiple fixing members 222 with the connection holes 112 of the seat portion 1. The resilient members 211 are hollow members and liquid or air is filled in the resilient members 211. The resilient members 211 have flexibility, when one resilient member 211 is compressed, the other resilient member 211 expands. Each of the resilient members 211 is a semi-circular member, a rectangular member, a square member or a polygonal member.
A seat pad unit 3 has a left pad 31 and a right pad 32, and the seat pad unit 2 is located on the seat portion 1. The left and right pads 31, 32 respectively has an engaging member 311/321 and a tubular member 312/322 connected to the underside thereof. The engaging members 311, 321 engage the seat pad unit 3 with the fixing frame 13. Each of the tubular members 312, 322 has a bearing unit 4 received therein which provides resistance when the left and right pads 31, 32 are pivoted about the transverse bar 132.
Each of the bearing units 4 has a bearing 41 and a C-clip 42. The bearings 41 are located in the tubular members 312, 322 and the transverse bar 132 extends through the engaging members 311, 321 and the tubular members 312, 322, the C-clips 42 is engaged with the grooves 131 of the transverse bar 132 to secure the seat pad unit 3 to the fixing frame 13.
When the seat portion 1, the adjustment device 2, the seat pad unit 3 and the bearing unit 4 are assembled, an outer portion 5 is mounted to the chair to have aesthetic outer appearance.
When the user's weight is evenly applied to the left and right pads 31, 32, the two resilient members 211 are balanced to support the weight of the user. The user feels comfortable because the resilient members 211. When the left pad 31 is applied by a force that is larger than that applied to the right pad 32, the resilient member 211 under the left pad 31 is compressed and the liquid or air flows to the resilient member 211 located under the right pad 32. The right pad 32 expands to support the right side of the user's body.
The driving device 4 may have only the engaging members 311, 321 and the tubular members 312, 322, and the bearings 41 and C-clips 42 are omitted. By the adjustment device 2, the desired function is also achieved.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
