ある。(Means and Actions for Solving the Problems) A seat cushion structure for a truck according to the present invention supports a cushion body by stretching a spring support member in the width direction of a frame formed by bending a pipe into a frame shape. In a seat in a track comprising a seat cushion made up of a seat cushion and a seat back mounted in a substantially vertical shape, left and right, side mountain-shaped front slip prevention portions are provided in the front portion of the frame-like frame, and the front slip prevention portion is provided. Is composed of a first inclined portion which inclines upward in the forward direction and a second inclined portion which inclines downward in the front end direction from the top of the first inclined portion. The spring support member is inclined and stretched in the same manner as the first inclined portion and the second inclined portion, and the front end portion of the frame is formed lower than the rear portion of the frame.

ている。Seat cushion (2) is an outer frame (3)
Is formed by bending a pipe into a frame shape, and a supporting member (4) made of an S-shaped spring is stretched between the left and right sides of the frame (3). (4)
A foam cushion body (5) is placed and formed on the top.
なお、フレーム（３）、発泡体製クッション体（５）は
表皮部材により被包されている。The frame (3) and the foam cushion body (5) are covered with a skin member.
フレーム（３）は、その側辺フレーム（3a）、（3a）が
中央から前方へ山形に折曲して前滑防止部を形成してい
る。The side frame (3a), (3a) of the frame (3) is bent in a mountain shape from the center to the front to form a front anti-slip portion.
側辺フレーム（3a）の前滑防止部たる山形状部（６）は
中央から前方へ上方向に傾斜する第１傾斜部（6a）と頂
部から前方へ下方向に傾斜する第２傾斜部（6b）から構
成されている。The mountain-shaped portion (6), which is the front anti-slip portion of the side frame (3a), has a first inclined portion (6a) that inclines upward from the center and a second inclined portion (inclined downward from the top to the front ( 6b).
第１傾斜部（6a）は側辺フレーム（3a）の後部よりも高
く形成されている。The first inclined portion (6a) is formed higher than the rear portion of the side frame (3a).
第２傾斜部（6b）はその前端部（6c）が側辺フレーム
（3a）の後部よりも低い位置に形成されており、着座者
の大腿部と第２傾斜部（6b）及び前端部（6c）との間に
おける上下方向の間隔が大きくなるように形成されてい
る。従って、第２傾斜部（6b）及び前端部（6c）と着座
者の大腿部との間における上下方向の間隔が大きいの
で、クッション性が良く、着座者が運転操作時に踏み込
んだ際、大腿部へ生じる圧迫感を減少させている。The front end portion (6c) of the second inclined portion (6b) is formed at a position lower than the rear portion of the side frame (3a), and the thigh of the seated person and the second inclined portion (6b) and the front end portion are formed. It is formed so as to have a large vertical interval with respect to (6c). Therefore, since the vertical gap between the second inclined portion (6b) and the front end portion (6c) and the thigh of the seated person is large, the cushioning property is good, and when the seated person steps on during driving operation, a large amount is obtained. It reduces the feeling of pressure on the thigh.
そして、第１傾斜部（6a）と第２傾斜部（6b）を形成す
る側辺フレーム（3a）間には夫々にＳ形ばねからなる支
持材（４）、（４）が張架して取付けられる。Then, between the side frame (3a) forming the first inclined portion (6a) and the second inclined portion (6b), the supporting members (4) and (4) made of S-shaped springs are stretched, respectively. Mounted.
前記第１傾斜部（6a）に設ける支持材（４）は第１傾斜
部（6a）と同様に傾斜して第１傾斜部（6a）間に張架し
て、着座者の前滑りを防止している。The support member (4) provided on the first inclined portion (6a) is inclined like the first inclined portion (6a) and is stretched between the first inclined portions (6a) to prevent forward slip of a seated person. is doing.
第２傾斜部（6b）の支持材（４）は第２傾斜部（6b）と
同様に傾斜して第２傾斜部（6b）間に張架して設けられ
る。The support material (4) of the second inclined portion (6b) is inclined like the second inclined portion (6b) and is stretched between the second inclined portions (6b).
第２傾斜部（6b）の支持材（４）は前方へ傾斜する第２
傾斜部（6b）に張架しているので、支持材（４）と着座
者の大腿部間の発泡体製クッション体（５）の肉厚が厚
くなり、大腿部への圧迫感を減少させている。The support member (4) of the second inclined portion (6b) is the second inclined forward.
Since it is stretched over the inclined part (6b), the thickness of the foam cushion body (5) between the support material (4) and the thigh of the seated person becomes thicker, and the thigh has a feeling of pressure. Is decreasing.
第１、第２傾斜部（6a）、（6b）の支持材（４）…は第
１、第２傾斜部（6a）、（6b）の各傾斜面に夫々配設さ
れている。The support members (4) of the first and second inclined portions (6a) and (6b) are arranged on the inclined surfaces of the first and second inclined portions (6a) and (6b), respectively.
尚、（７）はリフタ機構のリンクで、基端（7a）が側辺
フレーム（3a）の山形状部（６）の下方に位置する空間
部内に配設されている。従って、側辺フレーム（3a）に
山形状部（６）が形成されているので、山形状部（６）
の下方に設けた空間部内にリフタ機構のリンク（７）を
配設でき、空間の有効利用が図れる。Reference numeral (7) is a link of the lifter mechanism, and the base end (7a) is arranged in the space portion located below the mountain-shaped portion (6) of the side frame (3a). Therefore, since the mountain-shaped portion (6) is formed on the side frame (3a), the mountain-shaped portion (6) is formed.
The link (7) of the lifter mechanism can be arranged in the space provided under the space, and the space can be effectively used.
（考案の効果） この考案によれば、次の効果が生じる。(Effect of the Invention) According to this invention, the following effects occur.
着座者の尻部は枠状フレームの前滑防止部における
第１傾斜部に第１傾斜部と同様に傾斜させて張架したば
ね製支持材に引掛かかるため、着座者の前滑りが防止で
きる。Since the hip part of the seated person is caught by the spring support member stretched and stretched on the first inclined part in the front anti-slip part of the frame-like frame in the same manner as the first inclined part, the forward slip of the seated person can be prevented. .
着座者の大腿部と枠状フレームの前滑防止部におけ

などの操作性が良好になる。The thickness of the cushion body between the thigh of the seated person and the second slanted portion in the forward slip prevention portion of the frame-shaped frame and the spring support member stretched by being slanted similarly to the second slanted portion is Since it becomes thicker and the cushioning property is improved, the feeling of pressure on the thigh during driving is reduced. Furthermore, since the second inclined portion is inclined in the direction toward the front end portion and the front end portion is formed at a lower position with respect to the rear portion of the frame, when stepping on the brake petal or the like,
The directionality of the thigh becomes almost parallel to the second inclined part, and moreover,
Since the thickness of the cushion body corresponding to the front end portion is large and the cushioning property is good, the operability when the clutch petal or the like is deeply stepped forward is improved.
枠状フレームの前滑防止部を側面山形状にパイプを
折曲して形成しているため、山形状の下方に空間が生
じ、この空間に、リフターなどを設けることができ、こ
の空間の有効利用が図られる。Since the front anti-slip part of the frame-like frame is formed by bending the pipe into a mountain shape on the side, a space is created below the mountain shape, and a lifter etc. can be installed in this space. It can be used.
