Reference numeral 24 denotes an injection means of PPS (polyphenylene sulfide) which is the hard synthetic resin.

次に、この実施例１の作用を説明する。   Next, the operation of the first embodiment will be described.

表面７ａを粗した金属製のシート構造部材４の第２部材７を成形型２０内に入れて、射出成形することで、粗面に合成樹脂製の強度部材１１の脚部１１ａを強固に支持してなるので、前記強度部材１１が強固にシート構造部材４の第２部材７に支持してあることで、シート構造部材４の第２部材７の強度が著しく増大したにもかかわらず、強度部材１１が合成樹脂製であるので、軽量に出来るし、シート構造部材４の第２部材７自体を薄板にできる、という効果を奏する。   The second member 7 of the metal sheet structure member 4 having a rough surface 7a is placed in the molding die 20 and injection molded to firmly support the legs 11a of the strength member 11 made of synthetic resin on the rough surface. Therefore, although the strength member 11 is firmly supported by the second member 7 of the sheet structure member 4, the strength of the second member 7 of the sheet structure member 4 is remarkably increased. Since the member 11 is made of synthetic resin, the weight can be reduced, and the second member 7 of the sheet structure member 4 itself can be made into a thin plate.

また、前記強度部材１１は、硬質合成樹脂のＰＰＳ（ポリフエニレンサルファイド）よりなることにより、金属製のシート構造部材４の第２部材７に合成樹脂の強度部材１１が確実に一体化できる、という効果を奏する。   The strength member 11 is made of hard synthetic resin PPS (polyphenylene sulfide), so that the synthetic resin strength member 11 can be reliably integrated with the second member 7 of the metal sheet structure member 4. There is an effect.

更に、前記シート構造部材４の第２部材７は、鉄材よりなり、表面７ａの粗面の凹部１２内に前記強度部材１１の脚部１１ａが確実に流れ込んで、強固な固定が可能となる、という効果を奏する。   Further, the second member 7 of the sheet structure member 4 is made of iron, and the leg portion 11a of the strength member 11 surely flows into the rough concave portion 12 of the surface 7a, so that it can be firmly fixed. There is an effect.

更に、前記強度部材１１は、複数の連続した略ハニカム状をなすことにより、前記シート構造部材４の第２部材７に加わった衝撃荷重が分散し、確実な衝撃の吸収が出来る、という効果を奏する。   Further, since the strength member 11 has a plurality of continuous substantially honeycomb shapes, the impact load applied to the second member 7 of the sheet structure member 4 is dispersed, so that the impact can be reliably absorbed. Play.

更に、前記シート構造部材４の第２部材７の粗面は、ナノレベルの凹部１２であることにより、前記シート構造部材４の第２部材７の表面を触った人にとって、そこに凹部１２があることを感じさせないので、簡単な表面処理でよく、製造原価が安価になる、という効果を奏する。   Further, since the rough surface of the second member 7 of the sheet structure member 4 is a nano-level recess 12, the recess 12 is provided to the person who touched the surface of the second member 7 of the sheet structure member 4. Since it does not feel something, a simple surface treatment is sufficient, and the manufacturing cost is reduced.

更に、前記シート構造部材４の第２部材７に加わる荷重点は、シートベルトリトラクタ９の支持部であるリトラクタブラケット８により、自動車の急制動等によって大きな荷重がシートベルトを介してリトラクタ９の支持部であるリトラクタブラケット８に加わっても、該支持部であるリトラクタブラケット８を支持するシート構造部材４の第２部材７が合成樹脂製の強度部材１１によって強固にされているので、充分保持できる、という効果を奏する。 Further, the load point applied to the second member 7 of the seat structure member 4 is such that a large load is applied to the retractor 9 via the seat belt by a sudden braking or the like of the automobile by the retractor bracket 8 which is a support portion of the seat belt retractor 9. The second member 7 of the seat structure member 4 that supports the retractor bracket 8 that is the support portion is firmly held by the synthetic resin strength member 11 even if it is added to the retractor bracket 8 that is the support portion. , Has the effect.

前記実施例１では、荷重点として、リクライニング装置の支持部として説明したが、リクライニング装置の支持部に限定されるものではなく、リクライニング装置の支持部であってもよく、自動車の急制動等によって大きな荷重がシートバック２を介して図示しないリクライニング装置の支持部に加わっても、該支持部を支持するシート構造部材４の第２部材７が合成樹脂製の強度部材１１によって強固にされているので、充分保持できる。   In the first embodiment, the load point has been described as the support portion of the reclining device. However, the load point is not limited to the support portion of the reclining device, and may be a support portion of the reclining device. Even if a large load is applied to the support portion of the reclining device (not shown) via the seat back 2, the second member 7 of the seat structure member 4 that supports the support portion is strengthened by the strength member 11 made of synthetic resin. So it can be retained sufficiently.

また、前記実施例１では、シート構造部材４の第２部材７の材料について、鉄板として説明しているが、鉄板に限らず、アルミニウム、マグネシウム、銅、ステンレス、チタン、黄銅であっても良い。   Moreover, in the said Example 1, although the material of the 2nd member 7 of the sheet | seat structure member 4 is demonstrated as an iron plate, not only an iron plate but aluminum, magnesium, copper, stainless steel, titanium, brass may be sufficient. .
